Answer:
KINETIC ENERGY-K.E = 1/2 mv2. "Energy posses by a body by virtue of its motion is referred to as 'Kinetic Energy'". Kinetic energy depends upon the mass and velocity of body. If velocity is zero then K.E. of body will also be zero.

ANSWER
Units of K.E
=
Nm
−1
=Kgms
−2
m
=kgm

Let
(m)
a
(v)
b
αK.E
k(M)
a
(LT)
b
αK.E
K.E=k(M)
a
(L)
b
(T)
−b
by compairing
a=1
b=2
−b=−2
(a=1&b=2)
thus K.E
=k(m)
a
(v)
b
=kmv
