During projectile motion, the horizontal component of velocity:
Correct answer: C. Remains constant
- A. Changes with time
- B. Becomes zero
- C. Remains constant
- D. Increase with time
Explanation
The following is the solution: The horizontal component of velocity is the component of the initial velocity that is parallel to the ground. It determines the object's horizontal motion and remains constant throughout the entire flight. The horizontal velocity does not experience any acceleration since there is no horizontal force acting on the object (assuming no air resistance). As a result, the horizontal component of velocity remains unchanged during the entire trajectory.

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.
