Explain why a high-speed collision between two cars would cause more damage than a low speed collision between the same two cars.
At high speed, both cars have more kinetic energy. The greater the kinetic energy will result in more damage.

If a volleyball and a bowling ball are moving at the same speed, which one has the most kinetic energy? Why?
The bowling ball. The bowling ball will have more kinetic energy because it mass is greater.
500
A tennis ball and a bowling ball are moving and have the same kinetic energy. Which one is moving faster? Why?
The tennis ball. The tennis ball will have to have greater speed to compensate for the greater mass of the bowling ball.
