Explain by an example that a body may possess energy when it is not in motion.

A body can possess energy even when it is not in motion through potential energy. Potential energy is the energy stored in a body due to its position or configuration.
Example: A Stretched Rubber Band
Consider a rubber band that is stretched but not yet released.
• When the rubber band is stretched, work is done to pull it apart, which stores energy in the form of elastic potential energy.
• This energy is stored in the rubber band even though it is not moving.
• If you release the rubber band, the stored potential energy is converted into kinetic energy, causing the rubber band to snap back and move.
Explanation:
• The rubber band does not have kinetic energy (since it's not in motion) but it still has energy in the form of potential energy due to its stretched position.
• This demonstrates that a body can possess energy when it is at rest, as long as it is in a position or state that allows potential energy to be stored (e.g., compressed, stretched, elevated).
Conclusion:
The energy is stored in the body due to its position or configuration, not necessarily its motion.
