Projectile, when launched at 90 degrees to horizontal, its trajectory is:
Correct answer: D. Linear
- A. Parabolic
- B. Periodic
- C. Hyperbolic trajectory
- D. Linear
Explanation
When a projectile is launched at 90 degrees with respect to the horizontal, it moves vertically upward and then falls back down under the influence of gravity. Its trajectory is a simple vertical line, not a parabolic, periodic, or hyperbolic curve.

About Projectile Motion
Projectile motion combines uniform horizontal motion with vertically accelerated motion under gravity, assuming air resistance is neglected. Questions use the components of initial velocity to find time of flight, maximum height, horizontal range and position, while distinguishing projectile motion from general circular or one dimensional motion.
