⚙️ Work Calculator — Physics Tool
This calculator solves for Work, Force, Distance, Power, Time, and Kinetic Energy using standard physics formulas. All calculations follow SI units (Joules, Newtons, Meters, Watts, Seconds) with automatic unit conversion.
Definition: Work is done when a force causes displacement of an object. Work = Force × Distance × cos(angle). If the force is parallel to the motion, cos(0°) = 1 and Work = Force × Distance.
📐 Core Formulas
Work: W = F × d × cos(θ) — Joules (J)
Force from Work: F = W ÷ (d × cos θ) — Newtons (N)
Distance from Work: d = W ÷ (F × cos θ) — Meters (m)
Power: P = W ÷ t — Watts (W)
Time from Power: t = W ÷ P — Seconds (s)
Kinetic Energy: KE = ½ × m × v² — Joules (J)
📏 Unit Reference
Work / Energy: 1 J = 1 N·m = 0.2388 cal = 0.000278 Wh = 0.000948 BTU
Force: 1 N = 0.2248 lbf = 0.10197 kgf = 1 kg·m/s²
Distance: 1 m = 100 cm = 3.2808 ft = 39.3701 in
Power: 1 W = 1 J/s = 0.001 kW = 0.00134 HP
Angle: θ = 0° means force is fully in direction of motion (cos 0° = 1)
🌍 Real-World Examples
Pushing a box: 50 N force, 10 m, angle 0° → W = 500 J
Lifting a weight: 100 N force (gravity), 2 m height → W = 200 J
Car engine: 5000 J work in 10 seconds → P = 500 W = 0.67 HP
Moving car: 1000 kg at 20 m/s → KE = 200,000 J = 200 kJ

What Is Work in Physics?
In physics, work occurs when a force causes an object to move. If an object moves due to an applied force, work has been done on that object.
The work formula physics definition is:
Work = Force × Distance
This means work depends on two factors:
The force applied
The distance moved in the direction of the force
Using a work physics calculator or work equation calculator, you can instantly compute work without manually applying formulas.
Work Formula
The standard work done formula physics is:
W = F × d
Where:
| Symbol | Meaning |
|---|---|
| W | Work |
| F | Force applied |
| d | Displacement (distance moved) |
If the force is applied at an angle, the formula becomes:
W = F × d × cos(θ)
This is why many advanced work calculator force displacement angle tools include angle inputs.
