What is Power?
Power is a way to measure how fast work is done or how quickly energy moves.

We use something called watts (W) to measure power.

1 watt means that 1 joule of energy is used every second.

So, it's like saying if you use 1 watt of power, you're using a little bit of energy every second.

How is Power Different from Energy?

• Energy: This is what you need to do work. It’s measured in joules (J).
• Power: This tells us how quickly energy is used or how fast work happens.

How to Calculate Power
You can figure out power using this simple formula:

Power = Work ÷ Time

Here’s an example to make it clearer:
Let’s say you do 200 joules of work in 5 seconds.

You would calculate power like this:

Power = 200 J ÷ 5 s = 40 W

So, in this case, you would have 40 watts of power.
