## Definition

**Kinetic energy** is the energy of mass in motion. An object that has motion – whether it is vertical or horizontal motion – has kinetic energy.

Kinetic energy is a scalar quantity i.e. Kinetic energy does not have any direction

##### Types of Kinetic Energy

Type |
Motion |
Examples |

Mechanical Energy | Motion of macroscopic objects | machines, muscles, projectiles, wind, flowing water, ocean waves, sound, etc. |

Thermal energy | Random motion of microscopic particles of (molecules, atoms, ions) | Heat, fire, geothermal, etc. |

Electrical energy | bulk flow of charges(electrons, protons, ions) | household current, AC and DC circuits, lightning, etc. |

Electromagnetic radiation | disturbance propagating through electric and magnetic fields(classical physics) or the motion of photons (modern physics) | Radio waves, microwaves, infrared, light, ultraviolet, x rays, gamma rays |

## Formula

Kinetic energy of a moving body is equal to one-half the product of its mass and the square of its velocity

K.E._{(J)} = 1/2 * mass_{(kg)}[m] * Velocity^{2}_{(m/s)}[v]

**For Example:**

Determine the kinetic energy of a 1000 kg car that is moving with a speed of 18 m/s?

**Sol. :**

K.E = 0.5 * (1000_{(kg)}) * (18_{(m/s)})^{2}

**K.E. = 1.62*10 ^{5} Joules**

## Units

The standard unit of measurement for kinetic energy is the **Joule**. 1 Joule is equivalent to **1 kg*(m/s) ^{2}**
