A ball rolls across the floor. Because of friction, the ball will eventually slow down and come to a stop. Which of the following is evidence of energy transfer resulting from the change in the motion of the ball?

• Different surfaces create different amounts of friction.

• The ball moves in the same direction as it rolls across the floor.

• Energy sets the ball in motion.

• The ball and the floor gain a small amount of heat energy.
