Work Calculator
Work is done when a force moves an object. Calculate work, force or distance, including the angle between the force and the movement.

About the Work Calculator
Work is done when a force moves an object. Calculate work, force or distance, including the angle between the force and the movement.
How to use the Work Calculator
- Enter two of Force (F), Distance (d) and Work Done (W) and the Angle θ (0 means parallel).
- Press the matching Find button or Calculate.
Formula and method
W = F × d × cos θ
Worked example
A 100 N force moving an object 10 m in the same direction does 1,000 J of work.
Tips
- Work is measured in joules.
- Carrying a bag at constant height does no work against gravity because the force and movement are at 90°.
Frequently asked questions
When is work zero?
When there is no movement, or when the force is perpendicular to the movement.
