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. 30 degrees
- B. 45 degrees
- C. 60 degrees
- D. 90 degrees
Explanation: Range is proportional to sine of twice the launch angle, which is largest when twice the angle is 90 degrees, so the angle itself is 45…
Correct answer: 45 degrees- A. zero in every direction
- B. horizontal only, with the vertical component zero
- C. vertical only
- D. equal to the launch velocity
Explanation: Gravity acts only vertically, so the horizontal component of velocity is unchanged throughout the flight while the vertical component…
Correct answer: horizontal only, with the vertical component zero- A. 30 degrees
- B. 45 degrees
- C. 60 degrees
- D. 90 degrees
Explanation: Range is proportional to sin 2 theta, which is maximum when 2 theta is 90 degrees, that is at 45 degrees, assuming level ground and no air…
Correct answer: 45 degrees- A. increases steadily
- B. decreases steadily
- C. stays constant, because no horizontal force acts
- D. becomes zero at the highest point
Explanation: Gravity acts vertically only, so the horizontal motion is uniform while the vertical motion is uniformly accelerated, and treating the two…
Correct answer: stays constant, because no horizontal force acts- A. 15 degrees
- B. 30 degrees
- C. 45 degrees
- D. 60 degrees
Explanation: Range is proportional to sin of twice the angle and is greatest at 45 degrees, where sin 90 equals 1, so half the maximum range needs sin…
Correct answer: 15 degrees- A. Equal to initial velocity
- B. Half of initial velocity
- C. Equal to zero
- D. Minimum but not zero
Explanation: At the top the vertical component has fallen to zero, but the horizontal component is unchanged throughout the flight because no…
Correct answer: Minimum but not zero- A. Point of projection
- B. Highest point
- C. Between launching and highest point
- D. At all points
Explanation: The vertical component decreases as the projectile rises and is regained on the way down, so the speed is greatest at launch and again on…
Correct answer: Point of projection- A. Decrease
- B. increase
- C. Remains same
- D. None of these
Explanation: While a projectile rises, gravity acts downward and reduces its upward vertical velocity according to vy = uy - gt, where velocity is…
Correct answer: Decrease- A. Zero
- B. E/2
- C. E
- D. E/(2)1/2
Explanation: At 45°, the initial horizontal speed is v cos45° and the vertical speed is v sin45°.
Correct answer: E/2- A. Circular
- B. Made of two straight line segments
- C. Hyperbolic
- D. Parabolic
Explanation: After being thrown, the stone has constant horizontal velocity and constant downward acceleration due to gravity.
Correct answer: Parabolic- A. 4.00 s
- B. 5.00 s
- C. 6.00 s
- D. 7.00 s
Explanation: Taking upward as positive, the stone's height is h = 59.4 m + 19.6 m/s × t - 4.9 m/s^2 × t^2.
Correct answer: 6.00 s- A. Mass of the jumper
- B. Height of jump
- C. Angle of projection
- D. None
Explanation: For a projectile launched and landing at the same level, the horizontal range depends on the projection angle through R = u² sin(2θ)/g.
Correct answer: Angle of projection- A. equal to 45 deg
- B. equal to 90 deg
- C. equal to each other
- D. none of the above
Explanation: The range of a projectile is R = u² sin(2θ)/g. For 30 degrees, R = u² sin(60 degrees)/g, and for 60 degrees, R = u² sin(120 degrees)/g…
Correct answer: equal to each other- 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…
Correct answer: parabola- A. a gas filled ballon
- B. bullet fired from gun
- C. a football kicked
- D. a base ball shot
Explanation: A projectile moves mainly under gravity after being launched, as do a fired bullet, kicked football and hit baseball.
Correct answer: a gas filled ballon- A. 45
- B. 60
- C. 30
- D. none
Explanation: The range of a projectile on level ground is R = u² sin 2θ/g. This is maximum when sin 2θ = 1, so 2θ = 90° and θ = 45°.
Correct answer: 45- A. tan-1 ¼
- B. tan-1 4
- C. tan-1 ½
- D. tan-1 2

Correct answer: tan-1 4- A. H=gT2/8
- B. H=8T2/g
- C. H=8g/T2
- D. H=gT2
Explanation: For a projectile, the time of flight is T = 2u sin θ/g, while its maximum height is H = u² sin²θ/(2g).
Correct answer: H=gT2/8- A. E
- B. E/2
- C. E/4
- D. E/8
Explanation: At the highest point of its motion, the projectile will only have the horizontal component of its initial velocity.
Correct answer: E/4- A. Cos θ : 1
- B. Sin θ : 1
- C. Sin θ : cos θ
- D. Cos θ : sin θ
- E. Sin θ : tan θ
