Question
In projectile motion the horizontal component of velocity: a. Remains constant b. Decreases with time c. Changes uniformly d. Increases with time
Solution
The correct answer is:
a. Remains constant
In projectile motion, the horizontal component of velocity remains constant throughout the motion. This is because there are no horizontal forces acting on the projectile (assuming air resistance is negligible). The only force acting on the projectile is gravity, which acts vertically downward and does not affect the horizontal motion. Therefore, the horizontal velocity remains constant.
