Find the option that possesses ONLY Kinetic Energy:
  1. A stretched rubber band held in hand
  2. Water stored high up in a reservoir dam
  3. A glass marble rolling rapidly on a level floor
  4. A wound-up spring inside a toy car resting on a table

Solution

A rolling marble on the ground moves and has motion, so it possesses kinetic energy. The other options store potential energy due to state, shape, or elevated height.
