How to use the work done by a force calculator
Calculate work from force, displacement and the angle between them. Enter force, displacement, angle between force and motion in the fields above; the work, work are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- F — Force (N)
- d — Displacement (m)
- ang — Angle between force and motion (°)
Worked example
With force = 50 N, displacement = 12 m, angle between force and motion = 30 °, the calculator gives work ≈ 519.6152 J; work ≈ 0.5196152 kJ.
Frequently asked questions
What is the formula for the work done by a force calculation?
Work (J) = F × d × cos(ang). Work (kJ) = [Work] / 1000. Here F is force (N), d is displacement (m), ang is angle between force and motion (°).
What inputs do I need for the work done by a force calculator?
You need force in N, displacement in m, angle between force and motion in °. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
