Kinetic & Potential Energy Calculator
Calculate kinetic energy, potential energy, momentum, and power with full unit support.
⚡Kinetic Energy — KE = ½mv²
1,500 kg
27.8 m/s
Kinetic Energy
579,630 J
= 579.63 kJ
Momentum (p = mv)
41,700 kg·m/s
KE = ½ × 1,500 kg × (27.8 m/s)² = 579,630 J
🏔️Gravitational Potential Energy — PE = mgh
g = 9.81 m/s²
Potential Energy
7,848 J
= 7.848 kJ
PE = 80 kg × 9.81 m/s² × 10 m = 7,848 J
🔧Work-Energy Theorem — W = ΔKE
Work Done (W = ΔKE)
+200,000 J
Work done ON the object
⚡Power — P = W/t
