Physics Involved with Softball
Transcript of Physics Involved with Softball
different things when they are up to bat. But
they all involve the same principals. There are a couple different things that can
change the flow of the game. The weight & length
of a bat The different spikes
used in cleats The playing surface Red Infield Mix Classic Infield Mix Red Clay Infield Mix Normal Infield Mix Red Hop Infield Mix Red Limestone Infield Mix Beige Infield Mix There are 5 basic components involved with the softball swing 1. The Stance The Stance has a few different
areas involved that not every batter
follows to the T. -Balance is something every batter needs to have in order to be ready to hit the ball. - How much flexion is put on the back knee varies from hitter to hitter. As well as how straight they leave their front knee. -Weight Distribution can effect the way a batter hits the ball, most of the time the weight is divided 80% on the back leg and 20% on the front. 11. The Stride 111. Initial Movement This aside from the stride is the first athletic
movement the batter makes. The arms do like a power coil, where they wind
up before they make contact. The hips, legs, abs, and back is where the power comes from to drive the ball great distances. IV. Contact Point The collision between the ball and the bat is
considered 'glancing.' In order to drive the ball great distance, if the bat hits the ball in the center it causes just enough spin. M1 M1 M2 M2 Before After Bat Bat Ball Ball V1b V1b V2a V1a The different forces that are acting on the bat are gravity, drag, torque, and momentum from the arms. The drag caused from the air resistance is increased when the bat is moving through the air faster because of the swing. Torque is the force being put on the handle of the bat when a hitter is swinging. The sweetspot on the bat is approx. 5-7 inches from the end of the barrel.

Follow Through When you finish your swing, you are getting all the power you can out of the swing. If you stop your swing and 'colapse' your wrists after contact the ball won't go as far. The biggest thing that batters need to do in order to be successful at hitting, is make sure your entire swing in done in a nice fluid motion. Things to Remember Keep your head down on the ball even after contact. Don't peek to see where you hit it. Conservation of Momentum Fast Ball Even though it might seem like a fast ball is traveling straight from the pitcher's hand the the catcher's glove, gravity still cause the ball to drop. Rise Ball In order for the ball to over come gravity and float up into the air, the pitcher need to put a great deal of spin on the ball. Change Up The big thing with the change up is that it is much slower than the fast ball. Batters get fooled with a good change up if it is thrown the same way and looks to be coming toward them just like the fast ball. Curveball A curve ball is created when a ball is spinning. The faster flowing air under the ball creates less pressure, which forces the ball to dive or break. There are 3 physics rules that allow the pitcher to put certain spin on the ball. First is Magnus Effect F=1/2pv acl 2 Second is Bernoulli's Principle "The Magnus Effect: Why Pitches move." Home - TexasLeaguers.com - The Mechanics of Baseball.
