Energy Spiral Review 1

A soap box derby car at the top of a ramp has more ________________ energy and at the finish line at the bottom of the ramp it has more _________ energy

• potential, kinetic

• kinetic, potential

• potential, potential

• kinetic, kinetic

A ball is falling after rolling off a tall roof. The ball has

• kinetic energy only

• potential energy only

• both kinetic and potential energy

• neither kinetic or potential energy

Which type of energy transformation does NOT describe potential energy being changed into kinetic energy?

• Compressing a spring

• A ball falling off a shelf

• A bike coasting down a hill

• Releasing a stretched rubber band

The dotted line shows potential energy and the solid line shows kinetic energy.

If a car is traveling down the highway and is pulled over by a police officer, what changes must happen to the graph to show this situation?

• The dotted line would need to be vertical for a certain amount of time.

• The solid line would need to become horizontal on the x-axis for a certain amount of time.

• The solid line would need to reach zero on the y-axis at some point

• The dotted line would need to reach zero on the y-axis at some point.
