The amount of kinetic energy an object has depends on which feature of the object?

• its motion

• its position

• its gravity

• its height

Which statement best compares potential and kinetic energy?

• Objects always have more potential energy than kinetic energy.

What happens in terms of energy when a moving car hits a parked car, causing the parked car to move?

• The moving car transfers kinetic energy to the parked car.

• Kinetic energy in the moving car disappears.

• Kinetic energy in the parked car is created.

A thermometer is placed in water in order to measure the water’s temperature. What would cause the liquid in the thermometer to drop?

• The molecules in the water spread apart.

• The molecules in the thermometer’s liquid spread apart.

• The kinetic energy of the water molecules decreases.

• The kinetic energy of the thermometer’s liquid molecules increases.
