In projectile motion, the horizontal component of acceleration is:
Correct answer: A. Zero
- A. Zero
- B. 9.8m/s²
- C. 19.6m/s
- D. 4.9m/s²
Explanation
In projectile motion, the horizontal component of acceleration is zero. This is because no external force acts horizontally (assuming air resistance is negligible), so the horizontal velocity remains constant throughout the motion. The only acceleration is the vertical component, which is due to gravity.

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.
