Use this calculator to determine the velocity of a moving object in mile per hour, kilometre per hour, knot, metres per second or feet per second units, from the kinetic energy or work required to accelerate or decelerate an object, and its mass.

### Formula

The formula used by this calculator to determine the velocity of a moving object from the kinetic energy and velocity is:

v = (2 · KE / m)^{½}

#### Symbols

- v = Velocity of object
- KE = Kinetic Energy
- m = Mass of object

### Kinetic Energy (KE)

This is the kinetic energy of a moving object and represents the work done to accelerate it from rest, or decelerate it to rest.

### Mass (m)

This is the total mass of the object.

### Velocity (v)

This is the velocity or speed of the moving object.
