Fran is holding a ball in her hand. She raises the ball over her head. Then she lets go of the ball, and it hits the ground. Tell what happens to the potential and kinetic energy of the ball when she raises and then lets go of it.

• The potential energy increases when Fran raises the ball over the head. When Fran lets go of the ball, potential energy decreases and kinetic energy increases as the ball is falling.

• The kinetic energy increaes when Fran raises the ball over the head.When Fran lets go of the ball, kinetic energy decreases when the ball is falling.

• calculator and lamp

• speaker and radio

• lamp and toy

• toy and calculator
