💡 What is Power in Physics?

Power is how fast you do work.

🎯 Imagine This:

If two kids both carry the same heavy school bag up the stairs, but one does it faster, that kid used more power.

They did the same work, but faster = more power.

🧮 Easy Formula:

Power=WorkTime\text{Power} = \frac{\text{Work}}{\text{Time}}Power=TimeWork​

So if you do more work in less time, you have more power!

⚡ Units:

• Power is measured in Watts (W)

• 1 Watt = doing 1 unit of work in 1 second

🧒 Real Life Example:

Let’s say:

• You lift your school bag up to a table (that’s work!)

• If you do it in 2 seconds, and your friend does it in 1 second,

• Your friend used more power than you (because they were faster!)👍
