Rate of change of momentum is:
Correct answer: B. Force
- A. Impulse
- B. Force
- C. Torque
- D. Velocity
Explanation
The correct answer is Force. Newton's Second Law states that the force acting on an object is equal to the rate of change of its momentum, given by the equation F = ∆p/∆t. This means that force is directly proportional to how quickly momentum changes with time.Impulse represents a change in momentum but is not the rate of change of momentum. Torque is related to rotational motion and not linear change of momentum. Velocity describes the rate of change of position, not momentum.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
