Projectile when launched at 90 degrees to horizontal then 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 to the horizontal, its trajectory is a perfect vertical line. This means that the projectile will go straight up into the air and then come straight back down to the ground, following a linear path.

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.
