Quiz about Speed and Energy

Question 1

1) Which is evidence that a bowling ball has more energy when it is moving faster than when it is moving slower?

Accepted Answer

The bowling bowl can knock over more pins when it is moving faster than when it is moving slower.

Answer

The bowling ball has a larger mass when it is moving faster than when it is moving slower.

Answer

The bowling ball will reach the pins in less time when it is moving faster than when it is moving slower.

Answer

A bowling ball can knock over more pins than a soccer ball moving at the same speed.

Question 5

6) How can the speed of a dropped ball be increased?

Accepted Answer

Increase the height from which it is dropped to give it more potential energy.

Answer

Roll it down a hill instead to increase the amount of friction.

Answer

Drop a larger ball to increase the amount of friction.

Answer

Decrease the height from which it is dropped to give it more potential energy
