O_TEXTBLOCK_TEXT When the droid exerts <HL Topic=Force.tpc>FORCE</HL> on the spring and the spring compresses, the droid is doing <HL Topic=Work.tpc>WORK</HL> on the spring. The <HL Topic=Work.tpc>WORK</HL> is stored in the spring as <HL Topic=Potential.tpc>POTENTIAL ENERGY</HL>. As soon as the droid lets go, the spring's <HL Topic=Potential.tpc>POTENTIAL ENERGY</HL> is released and changes to kinetic energy pushing the droid backward. As the droid comes to a stop, the <HL Topic=Energy.tpc>ENERGY</HL> has not been destroyed, but changed to <HL Topic=Heat.tpc>HEAT</HL>.
E_QUEST1 When you swing on a swing, at what point is all your energy kinetic energy?
E_QUEST2 When does a bowling ball have kinetic energy?
E_QUEST3 When does a rubberband have the most kinetic energy?
D_TEXTBLOCK_TEXT The <HL Topic=Energy.tpc>ENERGY</HL> that a body possesses because of its <HL Topic=Motion.tpc>MOTION</HL> is called kinetic energy; it is active <HL Topic=Energy.tpc>ENERGY</HL>. The amount of kinetic energy depends on the <HL Topic=Mass.tpc>MASS</HL> of the object and the <HL Topic=Speed.tpc>SPEED</HL> at which it is moving.
