SPRING BOUNCE (Jan 2008, Nov 2009) When a ball bounces, the force on the ball increases to a maximum when the ball compression is a maximum, and then drops back to zero at the end of the bounce period. The force varies in a sinusoidal manner. When a spring bounces on its end, the force remains constant in time while a compression wave travels up to the top end, reflects, and travels .
