The time rate of change of linear momentum of a body is equal to:
Correct answer: A. Force
- A. Force
- B. Momentum
- C. Power
- D. Acceleration
Explanation
The force is defined as the rate of change of momentum which, if simplified, can be written as F=ma.

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.
