Work Calculator

Compute mechanical work done by a constant force over a displacement

Inputs

Formula: W = F · d · cos(θ). Work is positive when the force component aligns with the displacement.

0° = same direction, 90° = perpendicular (no work done).

Notes

  • 1 Joule = 1 N·m. To convert to ft·lbf, the calculator shows the value automatically.
  • If the angle exceeds 90°, work becomes negative (force opposes motion).
  • Only the component of force parallel to displacement contributes to work.
