Quick answer
Work is force times distance in the direction of motion; power is work divided by time.
W = Fd cos θ, P = W/t

Frequently asked questions
Why does a 90° angle give zero work?
A perpendicular force does not move the object along its direction of travel.
Is work the same as energy?
Work is energy transferred by a force — same units, joules.
What do I need to enter into the Work and Energy Calculator?
Just 4 values: force, distance, angle to motion, time taken. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Work and Energy Calculator work out the answer?
Work is force times distance in the direction of motion; power is work divided by time. It applies the formula W = Fd cos θ, P = W/t and shows the working so you can check each step by hand.
Is the Work and Energy Calculator free, and do I need an account?
It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
