What causes a basketball to bounce back up?
Basketballs bounce because of the pressurized air inside of them, gravity and Newton’s Laws of Motion. When you dribble a basketball, your hand and gravity both push the ball towards the ground (Law #1). The energy in the compressed air is transferred back to the ball pushing it back into motion.

A hard surface, like concrete or hardwood, hardly absorbs any, so most of the kinetic energy of the fall goes into bouncing the ball back up. A soft surface, like grass or carpet, absorbs more energy from the fall, so there’s less left to push the ball back up, and it bounces pretty badly.
Does a basketball bounce higher on concrete or wood?
