Question
Elastic potential energy can be seen in the rocks.
- True
- False
Hint:
Elastic potential energy can be stored in rubber bands, trampolines, springs, and an arrow drawn into a bow.
The correct answer is 'False'.
- Elastic potential energy is the potential energy stored by stretching or compressing an elastic object by an external force.
- So, the given statement is false.
