Kinetic energy - The energy possessed by virtue of its motion is said to be kinetic energy.

K E = 1/2mv2

Derivation : We know that,

W = f x s          

but f = ma

W = mas    ….. (1)

By 3rd eqn of motion,

v2 = u2 + 2as

at rest, u=0

v2 = 2as

as = 1/2 v2

Substituting in eqn 1, we get,

W = 1/2 mv2

Since work done is stored in kinetic energy.

so, K.E. = 1/2 mv2
