Formula
- m
- — Mass
- v
- — Velocity
What is the Kinetic Energy Calculator?
Kinetic energy is the energy an object possesses due to its motion — it grows with the square of velocity, which is why crash forces increase so dramatically at higher speeds.
How to use it
- 1 Enter the object's mass.
- 2 Enter its velocity.
Worked examples
Frequently asked questions
Why does doubling speed more than double crash energy?
Because kinetic energy scales with velocity squared — doubling speed quadruples kinetic energy, which is a core reason speed limits matter so much for collision severity.
