endobj Baseball Sweet Spot Science ScienceC 19.8K subscribers 19K views 6 years ago It turns out there's a lot of physics that goes into the sweet spot on a baseball bat! By clicking Accept, you consent to the use of ALL the cookies. Well also examine the impact that technology has had on the design of baseball bats in recent years and how it has helped players to hit the ball farther and harder. From that you can work out the speed and spin of the ball before and after it bounces. According to Newtons second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . Physics 1998 The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. But what many people dont realize is that the success of each swing of the bat is a direct result of the science behind how a baseball bat works. If the ball is at rest (when striking a ball off a T ) then. << When you hit a ball just right, you've hit it on one of the three "sweet spots" of the bat. 9-d\DA=cZ0Q>gIM$$;cd2O@&a;X,Nn_aP(]I1aRc(K1^ue> /P 8 0 R If you have two bats, each with the same weight the bat that carries more weight in the end will perform better in terms of speed. A simple introduction to the physics of the collision problem is given here. Despite the old timey aesthetic to wooden bats and sweet spots, scientists actually didnt know much of anything about the acoustics (yes, acoustics) of a bat until the 1980s and 90s. The illumination of the ordinaryof why the sky is blue or why the stars shineis not the least important role of physics and physicists. When you hit the sweet spot, the bat feels the best in your hand. PbLSZTLEE(8E@'*1mg_*eTnN*;*'V3+gm-EEetX%;Bo$ur2ss*N`.-!.kG_q6GDD' Baseball is based on the principles of Newtons laws of motion. /N 7 0 R Preliminary In order to indicate the origin of the baseball bats problem, the following preliminary are worth mentioning. >> Since the CM traces out a spiral rather than a circular path, the center of the circle moves, as the bat is swung, along the path traced out by the inner circle of black dots. In the late 1990s, the Crisco-Greenwald Cage Study found that bats made out of materials like aluminum perform better, for a number of reasons: First of all, it takes more skill. If the bat approaches a ball incident at speed vin then. According to one study, Brazils free-tailed bats have the fastest flight speeds ever documented by flying at 160 kilometers per hour in flight. White ash, sugar maple, true hickory, yellow birch, red oak, and Japanese ash are the six wood types that can be used in bats in Major League Baseball. endstream Manage Settings A question that is equally interesting is how the swing speed of each body segment varies as the bat speed varies and as the bat swing weight varies. (7Boo^^S:71(MN]ZQX/+Cbu.lK"p74pe1T%s.DY%&\1TdJhr54.M9au6>79n6`Q:4 /N 12 0 R See, the trouble with wood is that it vibrates. The bat was swung through an axis 143 mm from the knob end. The more general recommendation is that a teams best hitters should be grouped together in the batting order, rather than spread out, as this maximizes the chances of someone being on base when a good hitter comes to bat. Although playing a game of cricket requires a significant amount of time, it is filled with powerful and fast forces. The lines behind the bat, passing through the axis, mark out angles of 5, 10, 15, 20, 25 and 30 degrees. This includes both the length of the barreltop part of the batand its diameter The longer the barrel, generally, the larger the sweet spot for hitting the ball The standard diameter is 2 , and big barrel bats, allowed in some leagues, are 2 5/8. The ball bounces backward spinning counter-clockwise. } Concentration. The impact on a baseball bat is shorter (since the bat and ball are harder or stiffer), about 1 msec. A recoil of the bat occurs when a ball collides with the bat, causing it to push back against it with equal force. You can test your childs grip by having him or her hold the bat straight out in front of them, parallel to the ground, with their dominant hand. It minimizes vibration of the bat and results in the maximum energy delivered to the ball, meaning it travels the farthest. This cookie is set by GDPR Cookie Consent plugin. Published Mar 30, 2018 4:11 PM EDT. Upon impact with the ball, the rotation of the bat is reversed. Are heavy bats are more powerful than light bats? A pitch produces a turbulent wake of air behind the ball. In this article, well explore the various components that go into making a baseball bat, as well as how they work together to help a hitter put their best foot forward. Scientifically speaking, this is the weakest part of a wooden baseball bat. Where is the Sweet Spot on a Baseball Bat? If this is the case, the bats likely too heavy if it cant keep its grip in place for at least 20 seconds. Edd Roush holds the distinction of being the heaviest Major League Baseball player in terms of weight. on: function(evt, cb) { Since its vibrations that hurt your grip, the sweet spot is clearly the point where an impacting ball doesnt cause the bat to vibrate. /R [52 73 308 791 ] Thats the sport that demands the most from the athletes who compete in it. We call the point where a baseball bat has its nodes the sweet spot. The player will swing the bat from low to high, with too much bat speed resulting in fly balls. /V 7 0 R It is critical for any baseball player to know his or her bat weight before purchasing one; you must consider the weight of the bat in order to purchase it. listeners: [], Sniper Skin Announces Their Newest Partnership with Bassmaster Opens Pro, Briana Tucker! Curve Balls Sweet Spot / Corked Bats / Questec-MLB Zone Evaluation. ); The sweet spot is typically located around the center of the bat, and its size varies depending on the type of bat being used. The physics behind this phenomenon involves the transfer of energy from the bat to the ball. The ball will rotate about 1/2 a revolution from the initial grip to the release point, in about 0.1 sec or less. hitting a baseball is either painful or frustrating. /P 17 0 R Understanding the sizes of bats is critical to making the best choice for your game and the best bat for you. /R [52 73 308 791 ] And we divide that by Pi times 9.00 centimeters written as meters so centi is prefix meaning ten times minus two and we square that diameter. Baseball players were known to carve or whisk their own bats from various hardwoods during the early days of amateur baseball. I havent listened to different recordings of hits to see if theres a noticeable difference, says Russell. These are effectively the same as the vibrations that travel through the air and reach your ear, where you hear them as sounds. So, after a rainy day game, ensure your bat is dry before you store it. George has always been passionate about physics and its ability to explain the fundamental workings of the universe. When a batter hits a ball, the bat will rebound from the force of the collision. The wall of a bat is relatively heavy and returns only some of its stored elastic energy to the ball, keeping the rest to itself so it can ping as loudly as it wants to. Theres one where it feels good in your hands, one where the ball comes off the fastest. The three elements of a game of baseball are critical, and the game is built around Newtons laws of motion. The effect of the hands on the centre of percussion is described in American Journal of Physics, 72, 622-630 (2004). The second definition is where the ball comes off the bat fastest. As a result of the transfer of kinetic energy from the bat to the ball, it has increased mass and kinetic energy. Baseball bats are most commonly made out of wood, such as maple, ash, or bamboo. Learn how to add this technique to your swing while still keeping a balanced, relaxed approach to the ball. This is because physics plays a major role in how the bat interacts with the ball. The bat slows down after the collision (bat speed approximately cut in half), but the bat continues to rotate as a rigid object with no vibration. Articles may contain affiliate links which enable us to share in the revenue of any purchases made. The ball is spinning clockwise before it bounces and hits the granite block with backspin. The frequency is typically between 1000 Hz and 2500 Hz, meaning that the wall vibrates in and out 1000 to 2500 times in one second. Some results for an Easton BK7 aluminum bat are shown below in 13 QuickTime movie files, each about 1 Mb. The sweet spot is found on only one side of the bat. The vibration modes of a baseball bat are easily determined,3-5at least for a freely suspended bat ~e.g., one that is suspended by a light string!. A rough estimate would be that the ball rotates 1/4 revolution while it is in the pitchers hand, and while the hand moves forward say the last 0.2 m. If the hand moves forward at 10 m/s = 22.4 mph then it moves 0.2 m in 0.02 sec, so the spin rate would be 12.5 rev/s or 750 rpm. /R [316 73 572 791 ] But man, hit it right on the sweet spot and it feels like you are a baseball god. Near the end of the swing, the batter needs to exert a large negative couple on the bat, otherwise the bat will swing around too fast and strike the ball when it is aligned at the wrong angle. A high performance bat has a strong trampoline effect and hence a relatively large COR. /P 20 0 R The batter needs to exert a small couple to get the swing started, using equal and opposite forces on the handle, otherwise the barrel of the bat will get left behind. 10 0 obj They have a hoop vibration mode - alongside the typical bending modes - that extends their sweet spots. Rather, most coaches and others think in terms of wrist torque, which is probably much too small to provide the necessary large couple near the end of the swing The couple must come mainly from the two arms, not the wrists. Jessy is an avid baseball fan and writer for the popular website, Baseball Writes. Aluminum tubes are 24 to 35 inches (61 to 89 centimeters) long and 2 to 3 inches (5 to 7.6 centimeters) in diameter for making an aluminum bat. >> After completing his degree, George worked as a postdoctoral researcher at CERN, the world's largest particle physics laboratory. This is why it is important that baseball bats are made out of a hard material that can maximize the energy transfer while also reducing the risk of injury to the player. /P 11 0 R >> Near the end of the swing, the batter needs to exert a large negative couple on the bat, otherwise the bat will swing around too fast and strike the ball when it is aligned at the wrong angle. gF/(+GaKo$qneLWDrQ#;5\S(\$q'LM9bYJX9N;hHO_e;>`Y"/'J:I~> There is no simple physics answer to the heavy/light bat question here. That should sound like more of a thud, because youre not hearing the vibrations inside the wood. What is the biggest problem with wind turbines? Bats and Balls.- 3. /R [52 73 308 791 ] The technique here can be be used to measure the performance of any bat, at least at low ball speeds. A homerun hit right at the sweet spot would sound different than one hit off the target. If a player can maintain the same bat swing speed with a heavier bat, the heavier bat will produce higher batted ball velocity and an increase in distance. The impact of a bat and a ball is still not properly understood. For example, a 33-inch bat with a -3 rating weighs 30 ounces. Wood bats and aluminum bats have their own set of advantages and disadvantages, and the choice for the player is based on preference. It's where the wood grain is strongest. Join PopSci+ to read sciences greatest stories. Energy is lost during the collision if the bat vibrates. The sweet spots location for maximizing how far the batted ball travels after being hit can be calculated scientifically. << A baseball bat is shaped in such a way to have a "sweet spot." The sweet spot is due to the fact that the CP and the VN coincide. At the major league level, maple bats now account for 75% to 80% of all bats. An aluminum bat is much lighter than a wooden bat, increasing its range and allowing it to hit the ball farther. 5P8$ BaPR+"dUkbQ]YH`P. Alan Nathan has the world's best Physics of Baseball site at, Another very interesting Physics of Baseball and Softball site is maintained by Dan Russell at, Lloyd Smith at Washington State University has an excellent site on the physics and engineering of softball, at. But strong vibrations are generated for impacts near the tip. The ball rotated more than 1/4 but less than 1/2 of one revolution from one frame to the next, each frame being 0.04 sec apart. 24 0 obj By coupling the flexible bat to the ball via a parametrized fo. The sweet spot of a bat exists because bat vibrations are not excited significantly at that spot. /V 9 0 R Some hoop mode sounds are recorded in the following QuickTime Movies, using an aluminum bat and several aluminum tubes of various diameters and wall thickness. J,g]g+e/h_!_gCtO=0f)$P%cIi8Zdfc5&3j_8$7g. Also shown for comparison is a bounce off a heavy block of granite so that the COR of the ball can be determined. Demonstrating the sweet spot of the bat in a talk I gave at Wrigley Field for University of Illinois alumni in 1997. In theory, this should mean that a homerun hit right on the sweet spot would sound different from an off-target pop fly. A bat with an end loaded weight indicates that it weighs between 30 and 28 ounces. This website uses cookies to improve your experience while you navigate through the website. Why dies the bat vibrate inside or outside of the sweet spot? >> And though the term is almost always used exclusively to talk about baseball, the scientific principles that explain the sweet spot are actually true of tennis rackets, hockey sticks, and cricket bats as well. Contacting the Ball.- 8. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. /V 19 0 R >> /N 21 0 R The science of magnetism, while not as well-known as the science of moving energy when a bat hits a ball, is still important in the game. << It's this tendency to rotate that makes the bat's handle push back on or pull out of your hands. } 2.1. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. /ColorSpace [/Indexed /DeviceRGB 255 28 0 R] Wood bats hit farther than metal bats, which is the clear distinction between them. not apply to baseball or softball bats. It is not easy to find information on the actual rate of spin of a softball in flight, but it is relatively easy to measure, at least at low ball speeds and low spin speeds. When you use a heavier bat, the faster you hit the ball, the longer it will travel. Share your thoughts with us below! MLB . While the center of mass moves one way (nearly upward here), the handle moves the opposite way (nearly downward). Softer and less dense varieties of maple that are more likely to break have been banned by Major League Baseball. The film is shown here, taken at 25 frames/sec. 12 0 obj >> In theory, the ball bounces best for an impact at the center of mass of the bat, provided we can ignore bat vibrations. This force is required to change a 5 1/8th-ounce ball from a speed of 90 mph to a speed of 110 mph, this distorts the baseball to half its original diameter and the bat is compressed one fiftieth of its size.. In file A, the ball spins faster than in file B, both before and after the bounce. 3. Coefficient of Restitution = Relative speed of bat and ball after collision/ relative speed before collision, where "speed of bat" is the speed of the bat at the impact point. At other impact points, the impact is usually felt as a sting or jarring of the hands and forearm, particularly if the impact occurs at a point well removed from the sweet spot. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". Current research on the physics and science behind the game of cricket centers on the performance of the batsmen and bowlers. For a fastball, this wake gets pushed down, which then pushes the ball up .. >> The above results are more or less as expected, in that light bats can be swung faster than heavy bats. Potential energy is what might be called stored energy. The 232 g bat was swung at 45 radians/sec on average (by the batter in the film). The cookie is used to store the user consent for the cookies in the category "Performance". /V 21 0 R All this means that if goal of the bats design is to provide more power and speed, it makes it more likely to to crack and shatter. A hollow aluminum bat sounds a lot different to a solid bat since the wall of a hollow bat can vibrate in and out like a drum. While carbon dioxide gas is invisible, the very cold gas , Turbines produce noise and alter visual aesthetics. The ball seems to spin faster when it is fresh and slower after it has been used, but more experiments are needed to determine whether this is in fact correct. These cookies will be stored in your browser only with your consent. Hitting a baseball in the sweet spot on a baseball bat gives the best rebound and does not twist the handle of the bat in the hitter's hand. q is also called the apparent coefficient of restitution or ACOR. Those two are usually close, but theyre not exactly the same. The various supposed sweet spots effectively add up to a sweet zone, about two inches wide, right on the meat of the bat. /Height 99 A bat that is too light also hampers the development of a solid, level swing. For small swings of a pendulum, the incoming and outgoing speed of the pendulum bob is proportional to its horizontal displacement, so the relevant ball speed ratios can be measured directly off the film with a ruler. This point, usually 5-7 inches from the barrel end, does not move when the bat is vibrating in its first (or fundamental) bending mode. When Your Dream (Team/School/Job) Says "No". << Second, we give a simplified abstract form of bat which facilitates the description and modeling study. Bat speed depends on MOI, and is an important component of laboratory performance tests. What two factors determine the location of a baseball bat sweet spot? It is almost as easy as walking. This area is a product of physics, as the sweet spot is located at the center of percussion, which is the point on the bat that produces the least amount of vibration when hit. When a ball is hit in the sweet spot, the collision of the bat and ball creates a compression wave which travels through the bat and is then transferred to the ball, causing it to travel further. endobj The best wood for the Louisville Slugger bats to eat is northern white ash or maple, but wood from New York and parts of Pennsylvania can also be found. One question that can be answered this way is "Where on the bat does the ball bounce best?" The effect of the hands on the centre of percussion is described in American Journal of Physics, , 622-630 (2004). There are some models that include oak, but it is not as popular as maple or ash. As discussed earlier, missing the sweet spot can cause vibrations in the bat. Except, of course, when you hit the sweet spot. So, if you make sure the label is up, it means that you will be making contact with the edge of the grain which is the strongest part. The consent submitted will only be used for data processing originating from this website. There is enough physics in it to keep a PhD student busy for a few years, but it could also be done by any high school student as a simple introduction to the physics of baseball. Pitching Trajectories.- 5. endobj Choosing the right wood is essential for the proper performance of baseball bats. Explains r. cross, "the sweet spot of a baseball bat," american journal of physics, 66, 772-779. It would therefore not be surprising if a softball can be pitched at say 1000 rpm. Nathan hopes to test the theory of Robert Adair, a Yale University physics professor and baseball guru, who believes the subjective sweet spot sits on the node where the bat's lowest frequency vibrations drop out.

We and our partners use data for Personalised ads and content, ad and content measurement, audience insights and product development. Joe Jackson, a shoeless man, would prefer a custom-built bat known as Black Betsy. To get a better understanding of how science impacts your baseball bat, lets explore a few key scientific principles. endobj << Is it possible to hit heavier bats harder? << endobj Whenever an object is struck, it vibrates in response. Bamboo bats are the lightest of the three woods, making them great for players who need to swing fast. | << The hitch is, no one knows for sure how close the optimal spot for hitting is to the sweet spot that players know and love. At room temperature, it will go from a solid to a gas directly. /R [52 611 308 791 ] What is velocity of bullet in the barrel? Opines that close to where the point of percussion occurs is the "sweet spot." Explains that a net force hit on small mass will go farther than large mass. In case that didnt quite clear it up for you, lets break this down a bit. A similar question: The bumper on a pool table is at a height so that the pool ball does not skid when it hits it. The player has a unique preference for wood bats, which is why it is so important to select one. The cookie is used to store the user consent for the cookies in the category "Other. If you hit the ball on the "sweet spot" of the bat, you get the feeling of a solid connection with the ball. In fact, if the ball strikes the bat exactly on the ``sweet spot'' then the hitter is almost unaware of the collision. However. A paper on this subject can be downloaded. Batters know from experience that there is a sweet spot on the bat, about 17 cm from the end of the barrel, where the shock of the impact, felt by the hands, is reduced to such an extent that the batter is almost unaware of the collision. endobj The node is related to where the sweet spot is - where the bat does NOT bend or vibrate. Take a hammer in the other hand and gently tap the bat at various places along its length. A first guess would be at the tip of the bat since the tip travels the fastest. The experiment described below would be an ideal project on the physics of baseball, for any high school or University physics student. { >> Is swinging a bat potential or kinetic energy? If you hit a baseball somewhere other than the sweet spot, your hands will feel the vibrations. The physics of baseball Baseball players know from experience that there is a ``sweet spot'' on a baseball bat, about 17cm from the end of the barrel, where the shock of impact with the ball, as felt by the hands, is minimized. The bat was swung through an angle of about 30 degrees to strike the ball. Near the end of the swing, the bat swings so fast that the batter can no longer keep his wrists locked, and the centripital force on the bat is about equal to the weight of the batter. 5 0 obj Also shown for comparison is a bounce off a heavy block of granite so that the COR of the ball can be determined. In order to determine how each of the sweet spots influences the "feel" of the bat, measurements were made of the impact forces transmitted to the hands. He is a proud supporter of his local team, the Toronto Blue Jays, and loves to explore the history and culture of the sport. If the ball is struck at the sweet spot of the bat, then . /P 17 0 R The sweet spot of a bat exists because bat vibrations are not excited significantly at that spot. Through its shape, weight, and material composition, a baseball bat is designed to maximize a players power and accuracy while theyre at the plate. If you are 91 to 120 pounds, it is recommended that you use a 29-inch bat. If the ball didn't bounce at all then COR would be zero. Bud Hillerich, an apprentice woodworker in Louisville, Kentucky, began making Louisville Slugger bats in 1884. 18 0 obj The same thing happens when swinging a golf club, but it is not a well-known effect. Otherwise, the effective mass of the bat is less than its whole mass. (The first person to really investigate sweet spots did so on tennis rackets.) An impact at the fundamental node will not excite that mode, but it will excite the second mode. If the bat approaches a ball incident at speed v. Are heavy bats are more powerful than light bats? Baseball is a beloved American pastime, with millions of people playing the game recreationally or professionally each year. 25 0 obj >> /Length 459 How do you know if a bat is too heavy for a boy? Where is the best place on a bat to hit the ball? For that reason, the walls of a hollow bat need to be relatively stiff so they can vibrate at a frequency larger than 1000 Hz. As a smaller player, you will generally be able to achieve faster bat speeds with a lighter bat. The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. To understand such collisions it is important to first understand the physics of a collision between one ball and another. The ideal is the 110 turn model. . If you hit . On average, the sweet spot occurs between 5 and 7 in (12.7 and 17.8 cm) from the barrel end of the bat. The bat is 84 cm long, and has a mass of 849 gram. /V 15 0 R /N 15 0 R << The length, weight, and shape of the bat also affect its performance, as longer bats tend to have more power, and heavier bats tend to have more control. The ball rotated more than 1/4 but less than 1/2 of one revolution from one frame to the next, each frame being 0.04 sec apart. There is a difference between a bat and a racquet here, in that tennis strings are very light and give back to the ball 95% of their stored elastic energy. 19 0 obj Physics of Baseball & Softball R. Cross Published 22 February 2011 Physics, Education Preface.- 1. 28 0 obj This minimises discomfort to the hands caused by vibrations excited by the impact. Youre already losing about half the balls energy to deforming it (baseballs squish down to half their diameter as they impact a bat). The sweet spot of a baseball bat Rod Cross Physics Department, University of Sydney, Sydney 2006, Australia Received 10 November 1997; accepted 22 January 1998 The sweet spot of a baseball bat, like that of a tennis racket, can be dened either in terms of a vibration node or a centre of percussion.In order to determine how each of the sweet spots inuences the ''feel'' of the . /V 13 0 R 1 inch in length is huge. It was found, by measuring the frequencies of lots of aluminum tubes (see photo). /N 18 0 R It is not easy to find information on the actual rate of spin of a softball in flight, but it is relatively easy to measure, at least at low ball speeds and low spin speeds. >> The experiment can be done at low bat and ball speeds since the essential physics of the problem does not depend on the actual bat and ball speeds. He has been writing about the sport for over five years and is passionate about sharing his knowledge and enthusiasm for the game. A ball takes on a different shape as it is hit because the force of the bat pushing against it is multiplied by its mass. The physics of the three sweet spots of a baseball bat is discussed and the location of the ball impact point on the bat that leads to maximum ''power'' (greatest batted ball speed) is determined. Ball exit speed = (1 + q)V where V = bat speed at impact point just before the impact. The COR for a collision between the bat and the ball is less than 0.59 when energy is lost to vibrations, but can be greater than 0.59 if the bat has a trampoline effect on the ball. The hand moves forward faster than this in practice, so the spin rate could easily be around 1500 rpm. Also,.
