How to use this calculator
- Enter force (N) and distance (m).
- Optionally set the angle between the force and the motion.
How it works
Work = force × distance × cos(angle). At 0° the force is fully along the motion.
Worked example
20 N over 5 m. Work = 20 × 5 = 100 J.
Common mistakes
- Forgetting that force perpendicular to motion (90°) does no work.
- Mixing units — use newtons and metres for joules.
Frequently asked questions
Why include the angle?
Only the component of force along the direction of motion does work; cos(angle) accounts for that.
