Without Kinetic energy(basically), we couldn't have anything moving. Kinetic energy is the moving... The movement of something is Kinetic energy... Some uses (examples) of it: People walking around Cars moving Roller coaster ride Moving of a bike
There are many different forms of kinetic energy, but there are three that are most common. Linear Kinetic Energy (straight line motion) Rotational Kinetic Energy (Like a spinning top) Spring Kinetic Energy (A spring oscillating back and forth)
Kinetic Energy is the energy possessed by a body because of its motion. For example: A person walking, a thrown baseball, a crumb falling from a table, and a charged particle in an electric field are all examples of kinetic energy at work.
Kinetic energy is the so called energy in motion or movement. A good example for kinetic energy is a game of billiards wherein when the cue ball hits a ball, it will dramatically slow down and the ball it hits will receive the kinetic energy passed by the cue ball.
In a hydro plant the water has potential energy which turns to kinetic when it is allowed to fall into the turbine. Or in a gasoline engine or a jet engine, the potential chemical energy in the fuel is released by burning it and it results in kinetic energy of the vehicle.
