Question

3) The wound
a watch possesses potential energy. give scientific reason ​

Answer 1

Answer:

A wound spring has potential energy. The spring does not possesses kinetic energy until it is released and it starts to move. Hence energy in the form of potential energy is stored in the spring and when it is unwind it transfers its energy to the moving parts in the form of kinetic energy

Answer 2

Answer:

Since the body is in state of rest it possesses potential energy because it does not have any gravitational force acting on it and without the application of gravity a body can't possess position of rest. Thus there is no potential energy without gravitational energy.

➡.Thus a wound watch spring has potential energy.
