Use this calculator to determine the kinetic energy of moving object, or the work necessary to accelerate an object from rest, or decelerate a moving object to rest, in kilocalorie, joule, kilojoule, kilowatt-hour, electronvolt, british thermal unit, foot-pound or newton-metre units, with a specified mass and velocity.

### Formula

The formula used by this calculator to determine the kinetic energy or the work required to accelerate or decelerate a moving object from its mass and velocity is:

KE = ½ · m · v²

#### Symbols

- KE = Kinetic Energy
- m = mass of object
- v = velocity of object

### Mass (m)

This is the total mass of the moving object.

### Velocity (v)

This is the velocity or speed of the moving object.

### Kinetic Energy (KE)

This is the kinetic energy of a moving object and represents the energy which would be required to bring the object to rest or accelerate it from rest to the specified speed.
