Hi
Here is your answer,
KINETIC ENERGY
The energy possessed by a body by virtue of its motion is called ''KINETIC ENERGY''. In other words i can say that the amount of work done a moving object can do before coming to rest is equal to its kinetic energy.
∴ KINETIC ENERGY = 1/2mv²
where m is a mass and v is the velocity of a body
(1) A bullet fired from a gun can pierce a target due to its kinetic energy
(2) The kinetic energy of the fast stream of water is used to run water mills.
(3) The kinetic energy of air is used to run water mills.
(4) The kinetic energy of a hammer is used in driving a nail into a piece of wood.
→ The units and dimensions of KE are ''JOULE''( In SI) and [ML T] respectively.
→Kinetic energy of a body is always positive. It can never be negative.
Kinetic energy of a body depends upon the frame of reference.
For example:- Kinetic energy of a person of mass m sitting in a train moving with velocity v is [1/2mv] in the frame of earth and KE of the same person = 0, in the frame of the train.
Hope it helps you !
