At maximum height on the trajectory which component of projectile becomes zero?
Correct answer: C. Vertical velocity
- A. Acceleration
- B. Velocity
- C. Vertical velocity
- D. Horizontal velocity
Explanation
At the apex the vertical component of velocity is zero because upward motion has ceased instantaneously; horizontal velocity remains unchanged and acceleration (gravity) remains downward.

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.
