a stretched spring
a stretched spring

a spring traveling down a flight of stairs
a spring traveling down a flight of stairs

Answer 1

The correct response is:

a spring traveling down a flight of stairs

Kinetic energy is the energy that an object has due to its motion. A spring that is traveling down the stairs is in motion, thus it possesses kinetic energy. The other options involve springs that are either compressed, stretched, or stationary, which do not have kinetic energy unless they are in motion.
