Power is work being done faster or slower. If you are really strong, you have a lot of power. Wrestlers and strong fighters have a lot of power because they are really strong. A bug is not as powerful as a gorilla.

Power is measured in Watts. The formula to find Watts is Joules divided by Seconds.

Watts=Joules / Seconds

Let's try an example: A lightning bug has 200 Joules for 10 seconds. How much power does the lightning bug have?

We use this formula Watts=Joules divided by Seconds

The joules are 200 and the seconds is 10

(200)/(10) = 20

The lightning bug has 20 Watts of power! Good Job!
