How it works
The formula behind this calculator.
KE = ½ × m × v²
- m
- Mass (kg)
- v
- Velocity (m/s)
Kinetic energy scales with the square of velocity. Doubling the speed quadruples the energy — that's why high-speed collisions are so much worse.
Example: 1,000 kg car at 20 m/s (72 km/h) → 200,000 J = 200 kJ
Ref: Classical mechanics
Tips
- 💡 KE = ½ m v². Doubling the speed quadruples the kinetic energy — that's why high-speed collisions are so much worse.
- 💡 Mass in kg, velocity in m/s → energy in joules (J).
