The kinetic energy acquired by a mass (m) in travelling

The kinetic energy acquired by a mass (m) in travelling distance (s) starting from rest under the action of a constant force is directly proportional to

K.E. =	1	mv²
	2

Further, v² = u² + 2as = 0 + 2ad = 2ad
= 2(F / m)d

Hence , K.E. =	1	m × 2(F / m)d = Fd
	2

or, K.E. acquired = Work done
= F × d = constant. i.e., it is independent of mass m.
