In the projectile motion, the acceleration in the horizontal direction:
Correct answer: C. Is zero
- A. Remains same
- B. Varies with time
- C. Is zero
- D. Is positive
Explanation
Since horizontal component of velocity remains constant in projectile motion, therefore, the acceleration in horizontal direction is zero. Hence, option C 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.
