NEET Kinematics: 5 practice MCQs with answers

By the PrepMatic team · Updated 9 Oct 2026 · 4 min read

Kinematics describes motion without asking what causes it: displacement, velocity, acceleration, graphs, projectiles and relative motion. The questions are mostly short numericals that reward speed and clean sign handling. Try the five MCQs below, which are at NCERT Class 11 level, and read the explanations even where you got the answer right.

What this chapter covers in the NEET syllabus

The NMC syllabus has Kinematics as its own Physics unit. In NCERT it combines the Class 11 chapters Motion in a Straight Line and Motion in a Plane. The topics to cover are:

• Position, displacement, speed, velocity and acceleration, and the difference between distance and displacement.
• The three equations of motion for constant acceleration, and free fall under gravity.
• Position-time and velocity-time graphs, including area and slope.
• Vectors: resolution, addition, and the dot and cross product.
• Projectile motion and relative velocity in one and two dimensions.
• Uniform circular motion, which NCERT covers within Motion in a Plane.

Five practice MCQs on Kinematics

Question 1

A car starting from rest accelerates uniformly and reaches 20 m/s in 5 s. The distance covered in these 5 s is:

• A. 25 m
• B. 50 m
• C. 75 m
• D. 100 m

Question 2

Two projectiles are launched with the same speed, one at 30° and the other at 60° to the horizontal. The ratio of their horizontal ranges is:

• A. 1 : √3
• B. √3 : 1
• C. 1 : 2
• D. 1 : 1

Question 3

The position of a particle moving along a line is x = 3t² + 2t, where x is in metres and t is in seconds. Its velocity at t = 2 s is:

• A. 14 m/s
• B. 8 m/s
• C. 12 m/s
• D. 16 m/s

Question 4

A ball is thrown vertically upward with a speed of 20 m/s. Taking g = 10 m/s², the maximum height it reaches is:

• A. 10 m
• B. 40 m
• C. 20 m
• D. 30 m

Question 5

A swimmer who can swim at 4 m/s in still water heads straight across a river flowing at 3 m/s. His speed relative to the ground is:

• A. 7 m/s
• B. 5 m/s
• C. 1 m/s
• D. 3.5 m/s

Answers and explanations

1. B. The acceleration is a = 20/5 = 4 m/s². Then s = ½at² = ½ × 4 × 25 = 50 m. As a check, the average speed is (0 + 20)/2 = 10 m/s, and 10 × 5 = 50 m.
2. D. The range is R = u² sin 2θ / g. Since sin 60° = sin 120°, angles that add up to 90° (complementary angles) give the same range, so the ratio is 1 : 1. The maximum heights differ, though.
3. A. Velocity is the derivative of position: v = dx/dt = 6t + 2. At t = 2 s, v = 14 m/s. The equations v = u + at do not apply here because the acceleration is not given as constant.
4. C. At the top the speed is zero, so v² = u² − 2gH gives H = u²/2g = 400/20 = 20 m. The time to reach the top is 2 s, and the ball returns to the hand after 4 s.
5. B. The two velocities are perpendicular, so the resultant speed is √(4² + 3²) = 5 m/s. The swimmer reaches the opposite bank in the shortest time, but he is carried downstream.

How to prepare Kinematics

Kinematics rewards a small set of habits more than long theory sessions.

• Fix a sign convention before you start. Choose upward as positive, so a freely falling body has a = −g. Most wrong answers in free-fall problems come from mixing signs midway.
• Know when each tool applies. The three equations of motion hold only for constant acceleration. If the question gives x(t) or v(t) as a formula, differentiate or integrate instead.
• Read graphs as slope and area. The slope of an x-t graph is velocity, the slope of a v-t graph is acceleration, and the area under a v-t graph is displacement. If the velocity changes sign, the area gives displacement, not distance travelled.
• Memorise the projectile results and their meaning. Range, maximum height and time of flight come from the same three lines of algebra, so derive them once. At the highest point only the horizontal velocity u cos θ remains.
• Draw the vector triangle for relative motion. River-boat and rain-man problems become routine once you resolve velocities along and across the flow.

Aim to solve 15 to 20 numericals a day for a week, mixing graph, projectile and relative motion questions. Where Kinematics sits in your overall Physics plan is covered in the NEET Physics preparation guide, and the unit list is in the NEET syllabus.
