Work Calculator
Calculate work done (W=F×d), kinetic energy, potential energy, and power with automatic unit conversion
Note: Work = Force × Distance × cos(θ). θ=0° when force and motion are in same direction.

Work & Energy Formulas
W = F × d × cos(θ)
W: Work in Joules (J)
F: Force in Newtons (N)
d: Distance in meters (m)
θ: Angle between force and displacement
Example: F=100N, d=10m, θ=0° → W=100×10×1=1,000J
People Also Ask
⚡ What's the difference between work and energy?
Work is energy transfer (W=F×d), energy is the capacity to do work. They're measured in same units (Joules) and are related by Work-Energy Theorem.
🔍 When is work zero in physics?
Work=0 when: 1) No displacement (d=0), 2) Force perpendicular to motion (θ=90°), 3) No force applied (F=0). Holding object stationary does zero work.
📏 What is 1 Joule equivalent to?
1J = work done by 1N force moving 1m = energy to lift 100g apple 1m ≈ 0.239 calories ≈ 0.000000278 kWh.
🔄 How to calculate work with angled force?
Use W = F × d × cos(θ). For pushing at angle: only horizontal component does work. θ=0°: max work, θ=90°: zero work.
🌡️ What are common work/energy units?
Joule (J), calorie (cal, 4.184J), kilowatt-hour (kWh, 3.6MJ), electronvolt (eV, 1.6×10⁻¹⁹J), BTU (1,055J), foot-pound (1.356J).
⚙️ How is power related to work?
Power = Work ÷ Time. Higher power means same work done faster. 1 Watt = 1 Joule/second. Human power ~100W, car engine ~100,000W.
