Calculate power — the rate at which work is done or energy is transferred — from work and time.

How It Works

How Power Calculator (Physics) Works

Power is simply work (or energy) divided by the time it took — the same amount of work done faster represents more power, even though the total energy involved is identical.

FAQ

Frequently Asked Questions

What's the difference between work and power?
Work measures the total energy transferred, while power measures how quickly that transfer happens — lifting a box slowly or quickly involves the same work, but the quick lift requires more power.
