A moving material has kinetic energy. You can calculate the energy value by entering the material's mass and velocity.

Enter the mass in kg, and enter the velocity in m/s, then get the kinetic energy in J.

Kinetic Energy(J) = 1/2 x Mass(kg) x Velocity(m/s)^{2}

When the velocity becomes x2, then the kinetic energy becomes x4.

When the velocity becomes x10, then the kinetic energy becomes x100.

This means that a car with 60 mph has four times kinetic energy, compared to a car with 30 mph.

### Mile per Hour

The following calculator supports mph.
