Question

4 the star kicker transferred energy from her foot to the ball as she kicked it into the air. what happened to that energy? a the energy stayed in the ball until it reached its highest point, and then the ball lost all of the energy, causing it to fall back down and bounce on the ground. b the ball gained potential energy as it rose, then lost additional kinetic energy as it fell, causing it to generate new sound and heat energy as it bounced and was caught. c the kinetic energy in the ball turned into potential energy and stayed as potential energy as the ball returned to the ground, bounced, and was caught by another player.

Explanation:

When the ball is kicked, it has kinetic energy. As it rises, its height increases and its speed decreases, so kinetic energy is converted into potential energy. When it falls, potential energy is converted back into kinetic energy. When it bounces and is caught, some of the energy is dissipated as sound and heat energy due to friction and impacts. Option A is incorrect because energy is not lost completely at the highest - point. Option C is incorrect because potential energy does not stay as potential energy throughout the process.

Answer:

B. The ball gained potential energy as it rose, then lost additional kinetic energy as it fell, causing it to generate new sound and heat energy as it bounced and was caught.
