The rate of change of momentum of a body is proportional to the unbalanced force applied.
The rate of change of momentum of a body is directly proportional to the force applied and change in momentum takes place in the same direction as the applied force.
Which law states "The rate of change of momentum of a body is directly proportional to the force and takes place in the same direction as the applied force".
The rate of change of momentum of a body is directly proportional to the net external force acting on the body and takes place in the same direction as that of the applied force.
