Power (P)
Definition
Power represents how quickly work is done or how fast energy is transferred. It is calculated by dividing the amount of work done by the time it takes to do that work.
Analogy
Think of power as the speed at which you can complete your homework assignments. If you finish a lot of work in a short amount of time, you have high power. But if you take longer to complete the same amount of work, your power is lower.
