Kinetic and Potential Energy Intro

The graph shown could represent which of these?

• A book released from a height with the dotted line representing potential energy and the solid line representing kinetic energy.

• A book released from a height with the dotted line representing kinetic energy and the solid line representing potential energy.

• A pendulum released from a height with the dotted line representing potential energy and the solid line representing kinetic energy.

• A pendulum released from a height with the dotted line representing kinetic energy and the solid line representing potential energy.

In the figure, potential energy is being converted into kinetic energy from

• point A to point B

• point B to point C

• The only energy involved here is kinetic.

• Energy is not being converted.

Based on the diagram of a roller coaster car on a roller coaster track, what statement is true?

• The car at point A has more kinetic energy than the car at point C.

• The car at point C has less kinetic energy than the car at point B.

• The car at point C has more kinetic energy than the car at point B.

• The car at point D has less potential energy than the car at point B.

How would you describe the relationship between the mass of a car and its kinetic energy?

• As the mass of a car increases, its kinetic energy increases.

• As the mass of a car increases, its kinetic energy decreases.

• As the mass of a car decreases, its kinetic energy increases.

• There is no clear relationship between mass and kinetic energy.

Drag the relative energy labels to the correct point on the image.

• D

• Most PE

• B

• Mix of PE and KE, but of the points with a mix, this one has the most PE

• A

• Mix of PE and KE, but of the points with a mix, this one has a more equal mix of PE and KE

• E

• Most KE

• C

• A mix of PE and KE, but of the points with a mix, this one has the most KE
