Equations for Baseball

Some physical properites that occur in baseball are velocity, force, momentum, acceleration, friction, gravity, and waves. These properties help solve baseball problems. Listed below are some equations to do this.

Projectile Motion-

These equations help calculate the range, height and time of objects hit or thrown. Assuming that the air resistance is negligible, and gravity is constant.

1) Vx=Vcos(theta); where Vx=horizontal velocity and (theta) is the angle at which it was launched.

2) Viy=Vsin(theta); where Viy=initial vertical velocity.

3) dymax=.5gt1/22; where dymax=max height and g=gravity.

4) dx=Vxttotal; where dx=range and t=time.

Dynamics-

This is the study of forces and motion. And this is described by Newton's second law.

1) F=ma; where m=mass and a=acceleration.

2) k=Ff/Fn; where k=coefficient of friction and Ff=frictional force and Fn=normal force.

Kinematics-

This is the study of motion. And the following equations help describe linear motion.

1) v=d/t; where v=velocity and d=distance and t-time.

2) average velocity=(Vf + Vi)/2; where Vf=final velocity and Vi=initial velocity.

3) a=Vf-Vi/t; where a=acceleration.

4) d=Vit + .5at
