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. 2s
- B. 4s
- C. 8s
- D. 16s
Explanation: To solve this problem, we use the second equation of motion: S = ut + ½ gt2.
Correct answer: 4s62. A person travels a distance x = 20t+2At2, where A is a constant. The acceleration of the person is:
- A. A/4 ms^-2
- B. 4/A ms^-2
- C. 4 ms^-2
- D. 4A ms^-2
Explanation: The given equation for distance is x = 20t + 2At^2. To find acceleration, we need to differentiate this equation with respect to…
Correct answer: 4A ms^-2- A. 40m
- B. 80m
- C. 20m
- D. 100m
Explanation: Since,s = ut + ½ at²u = 0, a = gt = 4sg ≈ 10 ms-²Then,s = (0)(4) + ½ (10)(4)²s = 0 + ½ (10)(16)s = ½ (160)s = 80m
Correct answer: 80m64. A ball is dropped from the roof of a very tall building.What is its velocity after falling for 5.0s?
- A. 1.96 m/s
- B. 9.80 m/s
- C. 49.0 m/s
- D. 98.0 m/s
Explanation: List the known and unknown values.u = initial velocity = 0 m/sv = final velocity = ?m/sa = g = acceleration due to gravity = 9.8 m/s²t =…
Correct answer: 49.0 m/s- A. 1.3 m
- B. 2.5 m
- C. 5.0 m
- D. 10.0 m
Explanation: We must calculate the length of the tube, i.e distance traveled by the feather. We can use the formula for linear motion s = ut + 1/2at2.
Correct answer: 1.3 m
