Calculate Impact Energy

Impact is another word for kinetic energy. Here, the energy at an impact of a mass with a velocity can be compared to another mass and velocity. A comparison with a force is not possible. The units of both masses and velocities are equal, e.g. kg and km/h.

m1 * v1² = m2 * v2²

Mass 1:
Velocity 1:
Mass 2:
Velocity 2:

Please enter three values, the fourth will be calculated!

Example: a mass of 30 kg, impacting with 100 km/h, has the same kinetic energy than a mass of 3 metric tons, impacting with 10 km/h.
