Work Calculator
Solve W = Fd cosθ, build a multi-force work ledger, integrate measured force–position data, analyze spring work, or use the work–energy theorem — all with signed work, units, graphs and local processing.
Any-variable work solverWork, force, displacement or angle from the other three.
Variable F(x)Integrates measured data with zero-crossing-aware positive/negative work.
Work ledgerSum multiple angled forces and predict ΔK or stopping distance.
Spring + energyPotential-energy change, spring work and work–energy inversion.
Solve W = Fd cosθ for any one variable
Leave exactly one field blank. θ is the angle between the force vector and displacement direction.
Constant force work
Forces acting through one displacement

Magnitude
Angle (°)
Each angle is measured from the displacement direction: 0° does positive work, 90° does zero work, and 180° does negative work.
Piecewise-linear force–position data
One x,F pair per line, separated by comma, semicolon, tab or spaces. x values must be strictly increasing. Work is the exact integral of the assumed straight-line interpolation between entered points.
Ideal Hooke-law spring
x is measured from the spring’s unstretched equilibrium length. Positive/negative x indicate opposite sides of equilibrium; spring potential depends on x².
