Answer:
A
. The work done stretching a spring is transformed into stored energy in the spring
Explanation:
The work done stretching a spring is transformed into stored energy in the spring is clear indication of the law of conservation of energy.
The law of conservation of energy states that "energy is neither created nor destroyed but transformed from one form to another".
- In this problem, mechanical energy is used to stretch the spring.
- The mechanical energy is converted to stored potential energy.
This is an energy transformation process.
