Kinetic Energy:

Kinetic Energy

The energy possessed by a body by virtue of its motion, is called kinetic energy

Ewpression for kinetic energy :

KE = W =  12 mv2

Kinetic energy depends on frame of reference :

The kinetic energy of a person of mas m, sitting in a train moving with speed v, is zero in the frame of train bu  12 mv2 in the frame of the earth.
