Use this classical-physics calculation for a transparent first-pass result when the variables, reference frame, signs, and SI units match the stated ideal model.

Force (N)

Magnitude of the applied force in newtons.

Distance (m)

Displacement along the direction of travel in metres.

Angle (°)

Angle between the force and the displacement in degrees.

Compute mechanical work as force times displacement times the cosine of the angle between them (W = F·d·cos θ). The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Work (J)

The resulting work returned as a number.

• Point masses, constant acceleration, rigid bodies, uniform fields, negligible drag, and lossless transfers are common simplifying assumptions. Relativistic, quantum, rotational, dissipative, and uncertainty effects may require a fuller model.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Draw a free-body or energy diagram, check dimensions and limiting cases, retain signs and vectors, and compare consequential results with measurement or simulation.

• Centripetal Force Calculator

  Compute centripetal force as mass times squared speed divided by the circular path radius (F = m·v²/r).

• Force Calculator

  Compute force as mass times acceleration (F = m·a).

• Impulse Calculator

  Compute impulse as constant force multiplied by the elapsed time interval (J = F·Δt).
