At the maximum height on the trajectory which of projectile becomes zero?
Correct answer: C. vertical velocity
- A. acceleration
- B. velocity
- C. vertical velocity
- D. horizontal velocity
Explanation
At the maximum height of a projectile's trajectory, the vertical velocity becomes zero. When a projectile reaches its highest point, its vertical velocity momentarily becomes zero before it starts descending. This occurs because at the peak of its trajectory, the projectile momentarily stops moving upward before gravity pulls it back down.

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.
