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.
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 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)
