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.

- B. B
- C. C
- D. D
Explanation: As velocity of an object is increasing uniformly so it's acceleration is constant.
Correct answer: A25. If the slope of velocity time graph is not constant at different points,then body is moving with:
- A. Constant acceleration
- B. Average acceleration
- C. Increasing acceleration
- D. Uniform velocity
Explanation: Option C is correct.The v-t graph of an object with increasing acceleration is a parabola. .
Correct answer: Increasing acceleration- A. 4.9 m
- B. 19.6 m
- C. 29.4 m
- D. 39.2 m
Explanation: To determine the total distance covered by an object falling freely from rest, we use the following kinematic equation:* s = ut +…
Correct answer: 19.6 m- A. Uniform velocity.
- B. Positive acceleration.
- C. Negative acceleration.
- D. Instantaneous velocity.
Explanation: The slope of a velocity-time graph represents acceleration. If the slope is positive, it indicates positive acceleration, and if it is…
Correct answer: Instantaneous velocity.28. If the slope of a velocity-time graph gradually increases, then the body is said to be moving with
- A. Uniform velocity.
- B. Positive acceleration.
- C. Negative acceleration.
- D. Instantaneous velocity.
Explanation: The correct answer is positive acceleration. On a velocity-time graph, the slope represents acceleration.
Correct answer: Positive acceleration.- A. Variable motion.
- B. Instantaneous motion.
- C. Uniformly accelerated motion
- D. Non-uniformly accelerated motion.
Explanation: The correct answer is uniformly accelerated motion. This type of motion is shown on a velocity-time graph as a straight line, indicating…
Correct answer: Uniformly accelerated motion- A. I only.
- B. II only.
- C. I and III
- D. II and III
Explanation: The correct answer is II only. Car II's velocity-time graph demonstrates the acceleration pattern that meets the criteria described in the…
Correct answer: II only.- A. zero acceleration in region I.
- B. variable acceleration in region II.
- C. positive acceleration in region III.
- D. negative acceleration in region III.
Explanation: * Acceleration is represented by the slope of a velocity-time graph. * A positive slope indicates positive acceleration.
Correct answer: negative acceleration in region III.- A. 0.05 s.
- B. 0.25 s.
- C. 5 s.
- D. 20 s.
Explanation: * Frequency of the ticker tape (f) = 20 Hz * The diagram shows dots labeled P, Q, R, S, T.Calculations: * Calculate the time period (T)…
Correct answer: 0.25 s.- A. a < 0
- B. a = 0
- C. a > 0
- D. 0 < a < 1
Explanation: A) a < 0: This is correct. A decreasing distance between marks implies deceleration, which means the acceleration is negative.
Correct answer: a < 0- A. will be 10 m/s2.
- B. will be 25 m/s2.
- C. will be 50 m/s2
- D. cannot be determined.
