If two cars are moving at the same speed:

• they will have the same potential energy.

• the will have the same kinetic energy.

• the car with MORE mass will have MORE kinetic energy.

• the car with LESS mass will have MORE kinetic energy.

Describe how potential and kinetic energy are transferred or transformed in this image.

• As the balls are in motion, they have potential energy, and when they stop moving, they have kinetic energy.

• The kinetic energy from the air is being transferred into thermal energy when the balls collide.

• When the first ball is at the highest position, it has kinetic energy. When it falls, that kinetic energy is transformed into potential energy, which is then transferred to the next ball.

• When the first ball is at the highest position, it has potential energy. When it falls, that potential energy is transformed into kinetic energy, which is then transferred to the next ball.
