What is the definition of Kinetic Energy ?
The energy posses by a body due to its motion is called kinetic energy.
Kinetic energy of a body depends on its mass and speed.
KE = 1/2(mv2)
where m = mass of the body
v = speed of the body
SI unit of kinetic energy is same as that of energy i.e. Joules (J) and its derived unit is kg-m2 s-2
