Question
When we stretch a spring, the elastic potential energy of the spring:
- Increases
- Decreases
- Becomes Zero
- Becomes Infinity
The correct answer is: Increases
Elastic potential energy of spring increases when it is stretched due to hooke's law.
According to hooke's law, the force applied to stretch the spring is directly proportional to the amount of stretch.
Hence, the correct answer is (a) increases
