The energy is the capacity to do work. There are two types of
Energy:- Kinetice Energy:- It is defined as energy possessed by a body as a result of motion.
For Example:- If a javelin is in linear motion at its fullest speed, its kinetic energy will be more. When it is slow, it loses its kinetic energy. When it touches the ground, it has no kinetic energy. Kinetic energy also depends on the man or a thing.
Kinetic Energy = 1/2 mass x velocity (1/2 mv2)
Potential Energy:- It is energy which is stored up in a body because of its position.
For Example:- When a basketball is thrown upward, it gains in height. The movement of a ball comes to an end. It means the ball gets potential energy whereas kinetic energy goes away, when the basketball after reaching a certain height stops, its kinetic energy reduces to zero and the basketball has only potential energy.
PE = Mass x Gravitational Force x Height of the body from the ground (mgh).
