Calculation path

Calculate work done by a constant force over a straight displacement. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.

Calculation path

W = Fd cos(theta)

What you provide

What you provide

  • Force magnitude expressed in N, using the same scenario as the other inputs
  • Displacement magnitude expressed in m, using the same scenario as the other inputs
  • Force-displacement angle expressed in deg, using the same scenario as the other inputs

What you receive

What you receive

  • Mechanical work in J from the stated equation
  • A symbolic formula plus substituted working with your values
  • Visible assumptions, field guidance, and an authoritative learning reference

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

Force magnitude and angle are constant over the straight displacement.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
