Q. The kinetic energy acquired by a mass (m) in traveling distance starting from rest under the action of constant force is directly proportional to ?
β
Correct Answer: (B)
m°
Explanation: Work done by external forces = Change in kinetic energy Since particle starts from rest, its initial Kinetic Energy is 0. Therefore, K.E.=Fd It is given that force is constant. We see that Kinetic energy is independent of mass
