Physics of the Sweet Spot on a Baseball Bat :: physics sport sports baseball

The focus of my research is isolating and locating the lovable speckle on a baseball slam dance. I chose to avoid presenting natural data, but to examine the science that causesthis reaction. Participants of this sport probablyhave front hand or an intuitive knowledge of this saying. Locating the concoction spot can be done at home. A simple tryof your on can be done using either a wood or aluminumbat. The only apparatus required is a hammer. Gripping the batby the handle suspend perpendicular from the floor. employ a hammer, tapin various places on the barrel of the bat. As you approach thecenter of the barrel, vibration from the force provide diminish.Vibrational modes will be detected from the hand gripping the bat.Every baseball bat has a sweet spot. When a baseball hits a bat in the wrong place your hands sting, it means the force of the collision has provoke waves or vibrations called modes. When the ball is hit atthe inspissation it will non sting your hands. A mode generates two nodes or a invest of zipper displacement. A baseball bat consists of two major nodes this country is proverbially known as the sweet zone. Higherfrequency modes modify the ball speed, but can hardly be felt by the batter. Baseball bat vary in lengths,but generally the sweet spot is approximately 17 cm from the end of the barrel of a major league baseball bat. A collision near the node reduces the vibrations felt by the hand. The existence of thesweet spot is mainly because the vibrations do not agitate at that particular node. Impact on the first offnode will not excite the first mode, but will affect the second mode. Thus is true for the second nodesrelationship with the first mode. Close to where the point of percussion occurs is the sweet spot. match to astudy done by H. Brody at the Physics incision of the University ofPennsylvania, A bat of mass M and with initial velocity zero can be treatedas a free-body that is hit by a ball whose momentum changes due tothe interaction. At the time of percussion the bat will oscillate which indicatesa transferal of kinetic energy into vibrational energy and some kinetic energy is lost.When all this occurs it is an extremely warring action. The bat has amassive force on the ball ever-changing the direction and speed.EQUATIONS Newtons Second Law of Motion An unbalanced force causes an reject to move in the direction of the force.
