Basket Ball
When the basketball falls to the ground or is dribbled (a hand pushes down on the ball) the ball bounces back. This occurs due to the elastic collision that occurs between the basketball and the ground (or more specifically, the air particles in the ball and the ground). A perfect elastic collision is defined as a collision of particles in a closed system in which the total kinetic energy of the particles is conserved. The elasticity of a basketball can be determined by the height the ball rebounds. The basketball cannot achieve a perfect elastic collision with the ground but it can, however, achieve as much as 80% elasticity depending on the air pressure inside the ball. The air pressure of the ball greatly affects the elasticity of the ball and the conservation of energy of the ball. A tightly inflated basketball has a large amount of particles present inside the restricted space the surface of the basketball providesth
the force speed and angle at which the player releases the ball will determine if he make the shot
the players momentum carry's him up to make a dunk and gravity takes him backdown
