Work Calculator
Calculate mechanical work done. Enter force and distance, with an optional angle for W = Fd cos(θ).
How to Calculate Work
Enter Force
Input the force applied in Newtons. This is the push or pull on the object.
Input Distance
Enter the distance the object moves in meters while force is applied.

Perfect for physics students learning work and energy concepts.
Frequently Asked Questions
What is work in physics?
Work is energy transferred when a force moves an object. Work = Force × Distance × cos(angle). Measured in Joules (J).
When is work zero?
Work is zero when: no force is applied, no movement occurs, or force is perpendicular to motion (90° angle, cos(90°) = 0).
What is the unit of work?
The SI unit is Joule (J). 1 Joule = 1 Newton-meter. Other units: kilojoules (kJ), foot-pounds (ft-lb), and calories.
How does angle affect work?
Maximum work occurs at 0° (force parallel to motion). At 90°, work is zero. At 180°, work is negative (force opposes motion).
Is work the same as energy?
Work transfers energy. They have the same units (Joules) but work is the process of energy transfer, while energy is the capacity to do work.
