प्रश्न
Give one example of a body that has potential energy, in due to its state.
उत्तर
Potential energy of a body in the raised (or lifted) position depends on two factors :
- The greater the mass of the body, the greater the potential energy of the body, and
- the height of the body above the ground (greater the height of the body, the greater its potential energy.)
