A spring traveling down a flight of stairs has kinetic energy. Kinetic energy is the energy of an object in motion, and in this case, the spring is moving. The other options describe springs that are either at rest (still at the top of the stairs) or in a state of potential energy (compressed or stretched), but not in motion.
Which of the following has kinetic energy?
Responses
