Question

a pair of still keys are hanging above the ground.
what kind of energy is shown here?
spring energy
kinetic energy
gravitational potential energy

Explanation:

Spring energy is related to compressed/stretched springs, not hanging objects. Kinetic energy is for moving objects, but the keys are still. Gravitational potential energy depends on an object's height above a reference (like ground) and mass, which matches the still keys hanging above ground.

Answer:

C. gravitational potential energy
