## 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] * Velocity2(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*105 Joules

## Units

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