Based on the kinetic energy equation, which object has more kinetic energy? Assume both balls have the same mass.

• Ball moving at 5 m/s.

• Ball moving at 10 m/s.

According to the equation, you have to square the velocity (speed) of the object in order to calculate its kinetic energy. This simply means you multiply the number by itself. If the velocity (speed) of an object is 10, what is the result when you square the velocity?

• 20

• 100
