Free Work, Power & Horsepower Physics Calculator

In classical mechanics, work measures energy transfer when a force moves an object across a distance, while power measures the rate at which work is performed over time. Our free work and power calculator provides instant physics calculations. Compute mechanical work in Joules (J) or kilojoules (kJ), evaluate power output in Watts (W) and Kilowatts (kW), and utilize our horsepower from watts calculator to convert physics work into practical mechanical horsepower.

Mechanical Work & Power Formulas

W = F · d · cos(θ) for force F, distance d, angle θ | P = W / t.

Work W = F × d × cos(θ) | Power P = W / t | 1 HP = 745.7 Watts

Worked Step-by-Step Examples

Example 1: Applying 500 N Force over 20 Meters in 10 Seconds (θ = 0°)

"Calculate work done, power in Watts, and mechanical horsepower."

Steps:

Force F = 500 N. Distance d = 20 m. Angle θ = 0° (cos 0° = 1.0). Time t = 10 s.
Work W = 500 × 20 × 1.0 = 10,000 Joules (10 kJ).
Power P = 10,000 J / 10 s = 1,000 Watts (1.0 kW).
Horsepower = 1,000 / 745.7 = 1.34 HP.

Result: Work = 10,000 J (10 kJ), Power = 1,000 W (1.34 HP)
