Time into rate of change of momentum gives:
Correct answer: B. Impulse
- A. Force
- B. Impulse
- C. Acceleration
- D. Power
Explanation
Impulse J= Δp = (rate of change of momentum) × time = Favg × Δt; thus time multiplied by the rate of change of momentum equals impulse.

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.
