Explain what happens to the potential energy of a rock as it falls off the side of a cliff.

The potential energy decreases as the kinetic energy increases.

The kinetic energy decreases as the potential energy increases.

The kinetic energy decreases as the potential energy decreases.

The potential energy decreases as the kinetic energy decreases.

What variable would you change to increase the kinetic energy of the rolling marble?

A red marble is rolled down a ramp. It hits the blue marble. The red marble stops moving upon impact and the blue marble moves. Which statement best describes how the law of conservation of energy is demonstrated.

All of the kinetic energy of the red marble is transferred to the blue marble

No energy is transferred by the blue marble to the red marble

The red marble transferred all of its gravitational potential energy to the blue marble

The blue marble transferred all of its kinetic energy to the red marble

Students are investigating changes from potential to kinetic energy by rolling a marble down a ramp made by propping up a plastic ruler on a book and letting it roll down. Which of the following will change the potential energy the marble starts with?

Adding more books beneath the ruler to increase its height

Pushing the marble down the ramp

Switching the plastic ruler with a wooden one

Replacing the marble with a rock

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?

Both would have the same amount of K.E.

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

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

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

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?

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

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

Gravitational Potential Energy is being transformed into only kinetic energy.

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