How is power expressed in terms of work and time?

Power is defined as the rate at which work is done or energy is transferred over a period of time. The mathematical relationship that expresses this concept states that power equals work done divided by the time interval during which the work is performed. This means that if a certain amount of work is completed in a specific amount of time, the power can be calculated by taking the total work and dividing it by that time. This relationship allows for the comparison of how efficiently work is done; higher power values indicate that more work is done in less time.

In physical science, this understanding is fundamental for analyzing various situations where work is being performed, whether in mechanics, electrical systems, or other forms of energy transfer.
