Free fall / projectile motion physics project. Really like learning physics in school so I decided to play around with a project of it.
Velocity initial Y is the starting speed in the up-down direction. The ball's Y-velocity will change from its acceleration due to gravity. Velocity X is the speed in the left and right directions. It remains constant because of the lack of air resistance in projectile motion problems. X and Y are the starting X and Y values of the ball.
