A. The same force of same time causes the same change in momentum for different bodies.
B. The rate of change of momentum of a body is directly proportional to the applied force and takes place in the direction in which the force acts.
C. A greater opposing force is needed to stop a heavy body than a light body in the same time, if they are moving with the same speed.
D. The greater the change in the momentum in a given time, the lesser is the force that needs to be applied.
The correct answer is D. The greater the change in the momentum in a given time, the lesser is the force that needs to be applied.
