If an object moves with constant velocity, then its acceleration is _.
Correct answer: A. Zero
- A. Zero
- B. Non-zero
- C. Infinite
- D. None of these options are correct
Explanation
Acceleration is defined as rate of change of velocity, in constant velocity no change is occuring in velocity thus, option A is correct.

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.
