Question

select all the correct answers.
which two objects have stored energy?
□ a ball rolling on the ground
□ a small rock sitting on top of a big rock
□ a stretched rubber band
□ a stone lying on the ground

Explanation:

Stored energy (potential energy) is energy stored due to position or shape.

1. A rolling ball has kinetic (motion) energy, not stored.
2. A rock on a big rock has gravitational potential energy (stored due to height).
3. A stretched rubber band has elastic potential energy (stored due to shape change).
4. A stone on the ground has no significant stored potential energy relative to the ground.

Answer:

a small rock sitting on top of a big rock
a stretched rubber band
