Question 19

Two skateboarders are rolling down a hill. Both have the same weight and are using the same exact skateboards. If both skateboarders are going the same speed, which would have more kinetic energy?

Accepted Answer

Both would have the same amount of K.E.

Answer

The skateboarder closer to the bottom of the hill would have more K.E.

Answer

The skateboarder closer to the top of the hill has more K.E

Answer

It depends on how long it takes for them to reach the bottom.

Question 20

A small child goes down a sliding board at the park. he speeds up as he goes down the slide and notices that his bottom gets warmer! What energy transformations are taking place?

Accepted Answer

Gravitational potential energy is being transformed into kinetic and thermal energy.

Answer

Kinetic energy is transformed to gravitational potential energy and thermal energy.

Answer

Gravitational Potential Energy is being transformed into only kinetic energy.

Answer

No energy transformations can be calculated while he is going down the slide.
