Free Projectile Motion MCQs with Answers
55 Projectile Motion MCQs from Physics, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
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.

- 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.
Correct answer: Linear- A. Un-powered and guided.
- B. Un-guided and powered.
- C. Powered and guided.
- D. Un-powered and un-guided.
Explanation: A ballistic missile follows a ballistic trajectory, these missiles are propelled by a rocket engine for only the first part of its flight…
Correct answer: Un-powered and un-guided.- A. The angle of projection
- B. The initial velocity of projection
- C. The mass of the projectile
- D. Speed and mass of the projectile
Explanation: The horizontal range of a projectile is primarily determined by the angle of projection for a given initial velocity.
Correct answer: The angle of projection- A. v0 sin(θ) / g
- B. 2v0 sin(θ) / g
- C. v0 cos(θ) / g
- D. 2v0 cos(θ) / g
Explanation: The correct formula for the time of flight of a projectile is 2v0 sin(θ) / g, where v0 is the initial velocity, θ is the launch angle, and…
Correct answer: 2v0 sin(θ) / g- A. aS = vf2 - vi2
- B. 2aS = vf2 - vi2
- C. 2S = a(vf2 - vi2)
- D. aS = 2(vf2 - vi2)

Explanation: When a hunter aims at a bird in a tree, they should aim a little above the bird.
Correct answer: A little above the bird- A. Zero
- B. Minimum
- C. Maximum
- D. In between maximum and minimum
Explanation: In projectile motion, the velocity of a projectile can be broken down into horizontal and vertical components.
Correct answer: Minimum- A. 0
- B. 1/2g, horizontally
- C. g, upward
- D. g, downward
