Free Acceleration MCQs with Answers
65 Acceleration MCQs from Physics, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Acceleration measures the rate at which velocity changes with time, including changes in speed, direction or both. Work includes average and instantaneous acceleration, the relation a = Δv/Δt, uniform acceleration equations, and interpreting velocity time and displacement time graphs, with acceleration carefully distinguished from velocity.

- A. 40 m
- B. 80 m
- C. 160 m
- D. 320 m
Explanation: With uniform acceleration from rest the average velocity is half the final velocity, which is 10 m s-1, and over 8 s that gives 80 m.
Correct answer: 80 m- A. 15 m
- B. 30 m
- C. 45 m
- D. 90 m
Explanation: Using s equals half g t squared, the distance is half multiplied by 10 multiplied by 9, giving 45 m.
Correct answer: 45 m- A. 2 m per second squared
- B. 4 m per second squared
- C. 6 m per second squared
- D. 8 m per second squared
Explanation: Acceleration is the change in velocity divided by the time, so 20 divided by 5 gives 4 m per second squared.
Correct answer: 4 m per second squared- A. constant velocity
- B. zero acceleration
- C. changing velocity and therefore acceleration
- D. no force acting on it
Explanation: Velocity is a vector, so a continuous change of direction is a change of velocity even at constant speed, and the acceleration points…
Correct answer: changing velocity and therefore acceleration- A. Meter per secound
- B. meter per second square
- C. Both
- D. All
Explanation: Acceleration is change in velocity per unit time, so its SI unit is metre per second squared, written m/s².
Correct answer: meter per second square- A. Variable acceleration
- B. Constant acceleration
- C. Zero acceleration
- D. All of these
Explanation: Acceleration is the slope of a velocity-time graph. A parabolic curve has a changing slope, so the acceleration varies with time; the…
Correct answer: Variable acceleration- A. Speed
- B. Velocity
- C. Acceleration
- D. All of these
Explanation: The slope of a velocity-time graph is change in velocity divided by time, which is acceleration, measured in m/s².
Correct answer: Acceleration- A. 15 m
- B. 20 m
- C. 5 m
- D. 25 m
Explanation: For a body starting from rest, the distance covered in the nth second is s_n = 1/2 g(2n - 1).
Correct answer: 15 m- A. 1/6th
- B. 1/4th
- C. 1/8th
- D. None of these
Explanation: The Moon's gravitational acceleration is about 1.62 m/s², while Earth's is about 9.8 m/s².
Correct answer: 1/6th- A. acceleration
- B. distance
- C. force
- D. momentum
Explanation: The slope of a velocity-time graph is change in velocity divided by change in time, Δv/Δt, which is acceleration measured in m/s^2.
Correct answer: acceleration- A. acceleration is const
- B. acceleration is variable
- C. acceleration is zero
- D. velocity is zero
Explanation: A velocity-time graph parallel to the time axis has zero slope, so Δv/Δt = 0 m/s^2 and the acceleration is zero.
Correct answer: acceleration is zero- A. 4.9 m
- B. 19.6 m
- C. 39.2 m
- D. 44.1 m
Explanation: For a freely falling body starting from rest, distance is s = 1/2 gt². Using g = 9.8 m/s² and t = 2 s, s = 1/2 x 9.8 m/s² x (2 s)² = 19.6…
Correct answer: 19.6 m- A. straight inclined line.
- B. parabola
- C. inclined curve
- D. declined curve
Explanation: For constant acceleration, velocity changes according to v = u + at. This is a linear equation in time, so the velocity-time graph is a…
Correct answer: straight inclined line.- A. Vector quantity
- B. Scalar quantity
- C. Dimensionless quantity
- D. None of these
Explanation: Correct option is A.Acceleration is a vector quantity. This means that you include direction while describing acceleration.
Correct answer: Vector quantity- A. 200 m
- B. 400 m
- C. 800 m
- D. 1600 m
Explanation: The acceleration of the car is constant as it undergoes uniformly increasing velocity.
Correct answer: 800 m- A. Zero
- B. Constant magnitude but the varying direction
- C. Constant direction but the varying magnitude
- D. Varying magnitude and direction
Explanation: Centripetal acceleration is the acceleration experienced by an object moving in a circular path.
Correct answer: Constant magnitude but the varying direction- A. Toward the centre
- B. Always along the radius
- C. Irregular
- D. Circular in motion
Explanation: The net acceleration of a particle in circular motion is directed toward the centre of the circular path.
Correct answer: Toward the centre- A. 680 cm/s2
- B. 860 cm/s2
- C. 720 cm/s2
- D. 990 cm/s2
Explanation: The following is the solution:The formula for centripetal acceleration can be written as:a = v2/ r = rω2where v is the velocity of the…
Correct answer: 990 cm/s2- A. 40m/s2
- B. 4737.6m/s2
- C. 245m/s2
- D. 20m/s2
Explanation: Solution:a = rω²a = (0.30) (1200 × 2π / 60)² = 4737.6 ms⁻²
Correct answer: 4737.6m/s2- A. 30 rad/s2
- B. 30 rev/s2
- C. 3.14 rad/s-2
- D. 500 rev/s2
Explanation: To find the average angular acceleration, we convert the initial and final angular velocities to radians/second, then use the formula α =…
Correct answer: 3.14 rad/s-2Acceleration MCQs: common questions
