In projectile motion, the value of acceleration along x-axis is _.
Correct answer: A. ax = 0
- A. ax = 0
- B. ax = 10
- C. ax = 4
- D. ax = 40
Explanation
When considering projectile motion, the horizontal acceleration (ax) is usually negligible because there is no horizontal force acting on the projectile. The only force that may affect the horizontal acceleration is air friction, which typically has a minimal impact. Therefore, the correct answer is that ax = 0.

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.
