• Both the kinetic and potential energy increase.

• The potential energy decreases as the kinetic energy increases.

• Both the kinetic and potential energy decrease.

A football is thrown and rolls to a stop. Describe what happens with the kinetic energy.

• The kinetic energy is transferred from the ball to the ground

• The kinetic energy disappears.

• The kinetic energy is increased, causing the ball to stop.

A spacecraft is traveling to Mars, and a device is fired away in front of the spacecraft at a high rate of speed. What will happen to the energy in the device?

• The kinetic energy of the device will decrease on its own, and the device will come to a stop and just "float" there in space.

• The device will continue traveling at that rate of speed until it collides with another object, until solar winds affect its speed and direction, or until it gets close enough for the gravity of Mars to increase its kinetic energy.

• 
  The device will repeatedly bounce back into and off of the spacecraft due to the gravity between the spacecraft and the device as they exchange kinetic energy.

What happens with energy when someone shoots a bow and arrow?

• The potential energy of the bow is converted to kinetic energy when released, and that kinetic energy is transferred to the arrow.

• The kinetic energy of the bow is transferred to potential energy as the arrow flies to its target.

• Nothing happens with the energy.
