Free Displacement and Velocity MCQs with Answers
86 Displacement and Velocity MCQs from Physics, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Displacement is the directed change in position, while velocity is the rate of change of displacement and includes both magnitude and direction. The topic connects position-time and velocity-time graphs with average and instantaneous values, and distinguishes displacement from distance and velocity from speed.

Explanation: To find the overall average speed, we use the formula: Average speed = Total distance / Total time.
Correct answer: 48 ms-1- A. 5m/s
- B. 10m/s
- C. -5m/s
- D. 15m/s
Explanation: The relative velocity of the two cars with respect to one another can be found by adding their velocities.

- B. 13.3 ms-1
- C. 48 ms-1
- D. 40 ms-1
Explanation: V - overall average speedS - a total distancet - a total timeV = S/tS = V1*t1 + V2*t2 + V3*t3V1, V2, V3 - average speeds for each gear…
Correct answer: 48 ms-1- A. 2v
- B. √2v
- C. v
- D. v/√2
Explanation: c) v/√2 This option suggests that the average velocity of the man is v. This is the correct answer.
Correct answer: v/√2- A. 2.5
- B. 2.4
- C. 5
- D. 2.3
Explanation: We find out the average speed by using2v1v2/(v1+v2) = 12/5 = 2.4 km/h
Correct answer: 2.4- A. 10 sec
- B. 15 sec
- C. 20 sec
- D. 25 sec
Explanation: To calculateSpeed = 20m/sTotal distance = 100m +200m =300mTime = distance/speed = 300/20 =15s
Correct answer: 15 sec
