Work & Power: Work done by a force and how fast it is delivered. This free calculator solves for Work, power, force, time, efficiency and shows every step.
Work is energy transferred when a force moves something through a distance; only the component of force along the motion counts (the cosθ term). Power is how fast that work is done.
F = 100 N over d = 5 m in t = 10 s (in line with the motion). W = 100·5 = 500 J; P = 500/10 = 50 W.
Engine and motor ratings, electrical appliances, human-power output, machine-efficiency comparisons.
Work & Power uses the formula W = F·d·cosθ · P = W / t. Work done by a force and how fast it is delivered.
Choose which variable to solve for, enter the values you know (in any supported unit), and the calculator substitutes them into W = F·d·cosθ · P = W / t and shows every step of the working. It can solve for Work, power, force, time, efficiency.
