Kinetic energy can be defined as the energy possesed by body virtue of its motion
let a body of mass m moving with velocity u =0 when a force F is applied to move.let v be its final velocity
v*v-u*u=2as
since u=0,v*v =2as
a=v*v/2s
W=Fs=m.a.s
m.(v*v/2s).s
W=mv*v/2=1/2mv*v
this work done =KE
KE=1/2mv*v
