Vedclass · Answer

(B) According to the work-energy theorem,the work done by the net force on an object is equal to the change in its kinetic energy.Since the object starts from rest,the initial kinetic energy is $0$.Work done $W = F 	imes d$.Therefore,the final kinetic energy $K.E. = F 	imes d$.Since the force $F$ and the distance $d$ are constant,the kinetic energy acquired depends only on the product of the force and the distance.It does not depend on the mass $m$ of the object.Thus,the kinetic energy is independent of $m$.

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