The trajectory (or path) of a projectile is_________________?
Correct answer: B. parabola
- A. straight line
- B. parabola
- C. hyperbola
- D. circle
Explanation
A projectile has constant horizontal velocity and uniformly downward vertical acceleration due to gravity; combining these motions gives a parabolic path. The likely wrong choice is option a, because the initial straight-line direction is confused with the complete trajectory.

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.
