In physics, power is defined as the rate at which work is done. So power describes how quickly energy is transferred from one system to another when work is done.
- In mathematical terms, power is defined as the amount of work done per unit of time.
 - Power measures how quickly energy is generated or used.
 - When work is done on an object, energy is transferred to or from it, and power measures how rapidly this transfer occurs.
 - Essentially, power describes the efficiency or speed of energy conversion processes.
