## Kinetic Energy Formula

The formula for kinetic energy is:

**KE = 1/2 * m * v²**

- KE = Kinetic energy of an object (unit – joules, kJ, c, btu, erg, ev)
- m = mass of an object (unit- kilogram, g, lbs, oz)
- v = velocity of an object ( unit – m/s, km/h)

## How to calculate kinetic energy?

To calculate kinetic energy, Here are the steps to calculate KE:

- Determine the mass of the object
- Measure or calculate the velocity of the object
- Square the velocity by multiplying it by itself.
- Multiply the squared velocity by half of the mass.

## Solved Example

**For example** – if a car with a mass of 230 kg is moving at a velocity of 20 m/s, then calculate the kinetic energy of the car.

Given values,

Mass of car = 230 kilogram (kg)

The velocity of the car = 20 meters per second (m/s)

Kinetic energy of car = 1/2 *m *v² = 1/2 *230 *20² = 46000 joules

## What is kinetic energy?

The kinetic energy of an object is the energy that the object has due to its motion.KE is a scalar quantity, it has magnitude but not direction.

The SI unit of kinetic energy is the joule (J).
