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.

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.

• C

• Most PE

• A

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

• D

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

• B

• 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
