Kinetic Energy
"A moving object generally said to have kinetic energy"
Kinetic energy Definition

Kinetic energy is one of many types of energy that exist. This is energy generated because something is moving — the faster it's going, the more kinetic energy it has. A person sitting has no kinetic energy, but a person running like a maniac has tremendous kinetic energy:

The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed.

The amount of kinetic energy KE of an object in translational motion is equal to onehalf the product of its mass m and the square of its velocity v.

Kinetic energy is given as follows,
Kinetic energy = ½(mv2)
Kinetic energy Unit

Kinetic energy is measured in the units of joules.

One joule is the amount of work done when an applied force of 1 newton moves through a distance of 1 metre in the direction of the force.

Kinetic energy is a scalar quantity.
 Kinetic energy does not have a direction.
Examples of kinetic energy
Kinetic energy can be explained easily with a example . consider that you are in a hot room and you turn on the fan, what do you begin to feel? Air (wind).
The speedy movement of the fan's blades has kinetic energy, which is then transferred into air (wind) that you now feel.Other examples of Kinetic Energy include a moving car, moving wheel, and a moving arrow.
Types of kinetic energy
Three types of kinetic energy are available. They are

Rotational Kinetic Energy

Translational Kinetic Energy
 Vibrational Kinetic Energy
