How to use the Work Calculator
The Work Calculator works out your work done in an instant. Enter force and distance and the result updates as you type — it is free, needs no sign-up, and runs entirely in your browser so your figures stay private.
- Enter the force.
- Enter the distance.
- Read off your work done — the calculator updates automatically, with no button to press.
Formula
The Work Calculator uses the formula:
Work done = Force × Distance
Worked example
For example, with force of 100 N and distance of 5 m, the work done is 500.000.
| Force | 100 N |
|---|---|
| Distance | 5 m |
| Work done | 500.000 |
|---|

Key terms explained
- Force
- A push or pull on an object, equal to mass × acceleration (Newton's second law).
Frequently asked questions
Work equals force times distance moved in the direction of the force: W = F × d. A 100 N force over 5 m does 500 joules of work.
Joules (J). One joule is one newton of force acting over one metre.
No. If the distance is zero, no work is done, even if a large force is applied — like pushing a wall that does not move.
Only the component along the motion does work. This calculator assumes force and motion are in the same direction.
Enter the force. Enter the distance. Read off your work done — the calculator updates automatically, with no button to press.
