# Unit for Kinetic Energy

• 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.

• In S.I. unit, a J can be written in its most basic form as: (kg m^2)/(s^2).

• This is apparent from the kinetic energy equation: KE = (1/2) m v^2.

### Facts about kinetic energy

• The term “kinetic energy” was first coined by mathematician and physicist Lord Kelvin.

• If you double the mass of an object, you double the kinetic energy.

• If you double the speed of an object, the kinetic energy increases by four times.

• The word “kinetic” comes from the Greek word “kinesis” which means motion.

• Kinetic energy can be passed from one object to another in the form of a collision.

### 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 one-half the product of its mass m and the square of its velocity v.

• Kinetic energy is given as follows,

Kinetic energy = ½(mv^2)
