Momentum & Impulse

Poll

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?

• The optimally inflated one.

• The slightly flat one.

• They will both bounce to the same height since they both have the same mass, are made of the same material, and start with the same potential energy.
