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. Positive x Axis
- B. Negative x Axis
- C. Positive y Axis
- D. Negative y Axis
Explanation: The negative acceleration (deceleration) opposes the car's motion along the positive x-axis.
Correct answer: Positive x Axis- A. Linear
- B. Quadratic
- C. Cubic
- D. Decreasing Linearly
Explanation: If the velocity of a particle is varying linearly with time, the shape of the d-t (displacement-time) curve would be:B.
Correct answer: Quadratic- A. negative
- B. positive
- C. constant
- D. zero
Explanation: Linear acceleration, also known as tangential acceleration, is zero when a body is moving in a circular path because the object has…
Correct answer: zero44. If a car starts from rest and reaches a velocity of 20 m/s in a 10 m distance then acceleration is:
- A. 20 m/s2
- B. 10 m/s2
- C. 5 m/s2
- D. 2 m/s2
Explanation: v2-u2 = 2as 202 = 2 x a x 10 400/20 = 20 m/s2
Correct answer: 20 m/s2- A. velocity
- B. acceleration
- C. position
- D. momentum
Explanation: In uniform circular motion, the change in velocity is 0.The formula for acceleration is;a = change in Velocity/change in timeAs there is…
Correct answer: acceleration- A. Non-uniform
- B. Discrete
- C. Instantaneous
- D. Uniform
Explanation: If a body's speed increases equally in equal intervals of time, the time rate of change of speed is known as uniform acceleration.
Correct answer: Uniform- A. Negative
- B. Positive
- C. Zero
- D. None of these options are correct
Explanation: Option B is correct since when velocity increases acceleration will be positive as acceleration is the rate of change of velocity with…
Correct answer: Positive- A. Velocity
- B. Acceleration
- C. Position
- D. Momentum
Explanation: In uniform circular motion, the magnitude of linear velocity remains constant although its direction changes every instant.
Correct answer: Acceleration- A. A car speeding up as it moves southward
- B. A car moving southward at a constant speed
- C. A car slowing down as it moves northward
- D. A car slowing down as it moves southward
Explanation: The rate of change of velocity with respect to time is known as acceleration.
Correct answer: A car slowing down as it moves northward- A. Highest
- B. Lowest
- C. Middle
- D. None of these options is correct
Explanation: Firstly, at the highest point, all kinetic energy has been converted to gravitational potential energy so, there is a lack of kinetic…
Correct answer: Highest- A. Away
- B. Towards
- C. Normally
- D. Tangentially
Explanation: The word "centripetal" also means center-seeking/towards the center. The centripetal acceleration always acts towards the center of the…
Correct answer: Towards- A. Linearly
- B. Remains constant.
- C. Doubles.
- D. Decreases parabolically.
Explanation: The correct answer is Linearly because when a ball is thrown upward, it experiences a constant acceleration due to gravity which acts…

Explanation: Explanation:The slope of the velocity - time graph is equal to acceleration.
Correct answer: Straight line- A. Variable acceleration
- B. Uniform acceleration
- C. Uniform velocity
- D. Negative acceleration
Explanation: The correct answer is uniform acceleration. This is because the definition of uniform acceleration is when the velocity of a body changes…
