At the Sports Action Center you will get a chance to challenge other dens/patrol/crews to friendly competition on the human foosball court or in one of our GaGa ball pits. How It Works: In both of these sports, the main action is hitting or kicking a ball. What happens when you strike the ball involves both Newton’s third law of motion and the concept of elastic and inelastic collisions. Newton’s Third Law of Motion: You may already be familiar with this law which, simply put, states that for every action, there is an equal and opposite reaction. You see this when you hit or kick the ball which then moves away from your foot in the opposite direction. Forces always act in pairs, so striking the ball forces it to move away from your hand or foot. Elastic and Inelastic Collisions: An elastic collision is one in which there is no loss of kinetic energy in the collision. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy. Most collisions are neither completely elastic nor inelastic. When you hit or strike the ball, for example, some of the energy is converted to sound so that kinetic energy is not conserved. Learn what happens when you kick a ball.
