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.

The total kinetic energy of two cars is measured before and after they crash into each other. The total kinetic energy of the two cars after the crash is less than the total kinetic energy before the crash. Which of the following best explains the loss of kinetic energy?
Some of the cars' kinetic energy was converted to sound and heat energy.
Both of the cars were bring pulled downward by the force of gravity.
The cars will eventually stop moving, which shows that energy is always lost.
The car with more mass gave up its kinetic energy to the car with less mass.
