How to Calculate Work Done
What is Work Done?
A work-energy calculator computes the work done by a force over a displacement using W = F×d×cos(θ), where θ is the angle between force and motion. Work measured in joules (J) represents energy transfer — lifting a 10 kg box by 1 m requires 98 J of work against gravity.
Step-by-Step Guide
- 1W = F*d (direction of motion)
- 2Unit: Joule = N*m
- 3W = F*d*cos(theta) if angled
Worked Examples
Input
