You have two basketballs.

One is properly inflated to the NBA standard optimal pressure of 8 psi.

The other is a inflated to slightly suboptimal psi of 6.5 psi.

If you drop two basketballs from the same height above the gym floor, which basketball will bounce higher?

Two balls with identical mass, released from the same height on a ramp, roll down the ramp and hit a standing wooden 2x4. Which will knock over the wooden block?
