FC: The Physics of Softball By Edison Thalmen Nohely Cantu Alyssa Rosenthal & Josie Lopez
1: Pitching with a softball and a smooth ball is totally different. Its different by the air flowing around the ball. the flight of a smooth ball to the molecules travel behind the ball, is less than the perssure in front. When the ball has stiches as in a softball, turbulence occurs where the stiches are. The turbulence causes the air to stick to the ball just a little longer and reduces the wake which reduces drag.
3: Bunting: Normal Force is being applied on Alyssa R by standing in bunt position. Applied Force is being put on the bat by tapping the ball on point of contact. Air resistance is taking place by the ball coming to Alyssa R. Inertia is taking place by the ball still moving in the air. This is Newton's first law of motion; abody of motion will stay in motion unless an outside force acts upon it.
5: Batting: Force Normal is being applied in her batting stance. Force Applied is being used in her batting swing- she pushes the bat, making contact with the ball. Newtons third law of motion is being demonstrated; For every action there is an equal but opposite reaction. The Sweet Spot: when hitting the ball on the sweet spot the ball will go further. When the ball is not hit on the sweet spot the bat will vibrate. The reason for
6: the vibration is because the when swing the bat looses energy and momentum therefore not going as far. The sweet spot is located on 5-7 inches from the end of the barrel.
7: Having the different weight of the bat totally makes a different in the swing and how far it will go. | The less mass of the bat the more quickly it will swing. that means it will have less inertia. Nevertheless it will have less effetive collision between the bat and the ball. this demonstrates newtons 2nd law of motion;the greater the mass, the more force is needed to accelerate that mass
9: Catching: Force Normal is being applied on Alyssa. Air Resistance is being applied on the ball. The inertia is pushing the ball towards Alyssa. When catching a ball, the ball has inertia. This demonstrates newtons first law of motion; that a moving object will keep going until something stops it, the gravity in the air brings the ball down. In the seconds the ball goes straight the inertia is taking place.
11: Throwing With No Lower Body: Force Normal is being acted upon Alyssa. When the ball leaves her hands Air Resistance is taking place. Throwing using only your upper body gives you less momentum. This reduction of momentum results in a less powerful throw. This is an example of Newton's 3rd Law of Motion. The reason is the opposite reaction from having your lower body isolated is a weaker throw.
12: Elbows Up! When throwing with your elbows up, it helps with your throwing. Why? the reason is because the proper way to throw a ball is to have your arm in a 90 degree angle and fallow with you hand pointing to your target and then once relesing the ball you fallow through with the hand going to the oppistie direction. With having your elbow up and using your lower body (legs) you will be able to throw the ball farther.
15: Grounders: Force Normal is being applied on Alyssa. The Friction Force of the grass slows the ball down on its way to Alyssa. Applied Force was used to roll the ball towards Alyssa. This demonstrates Newton's 1st Law Of Motion; a body in motion will stay in motion unless an outside force acts upon it. The ball would have kept rolling had Alyssas glove not stopped it. However, eventually the friction would slow the ball to a stop.
17: Pitching: Force Normal is being applied to Josie. Force Applied is were Josie is flicking the ball out of her hands. Air Resistance is the air pushing back on the ball. Inertia is the ball leaving Josie's hand towards homeplate. This shows Newton's 1st Law Of Motion; That a body in motion will stay in motion until an outside force acts upon it.
19: Graph: On page 18, you will see a Time Over Distance graph. Explaining how far a softball can travel over time. Here the thrown softball traveled an average of .94 milliseconds per foot.
