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.$W = \Delta K.E. = K.E._{final} - K.E._{initial}$Since the body starts from rest,the initial kinetic energy $K.E._{initial} = 0$.Thus,$K.E. = W = F \cdot d$,where $F$ is the constant force and $d$ is the fixed distance.Since both $F$ and $d$ are constant,the kinetic energy $K.E.$ is independent of the mass $m$ of the body.

$A$ body starting from rest is moved by a constant force for a fixed distance. The kinetic energy of a body of mass $m$ is proportional to:
