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.

- C. 80 km/h
- D. 180 km/h
Explanation: Here the two buses are moving in the opposite directions Their speeds are u=100 km/hr and v=80 km/hr ∴ Relative speed =(u+v) km/hr…
Correct answer: 180 km/h- A. Along the tangent
- B. Perpendicular to the slope
- C. Parallel to the radius
- D. Anti-parallel to the radius
Explanation: The tangent to the curve at a given point represents the direction of instantaneous velocity at that point.
Correct answer: Along the tangent- A. Velocity
- B. Displacement
- C. Acceleration
- D. Distance
Explanation: The slope represents the rate of change of displacement with respect to time, which is the definition of velocity.
Correct answer: Velocity- A. m/s2
- B. m/s
- C. m
- D. 1/s
Explanation: Option A: m/s^2: This unit represents meters per second squared and is the unit of acceleration.
Correct answer: m/s- A. With different sizes of triangles drawn
- B. At a different point on curve
- C. At the start and end of the curve
- D. All of these options are correct
Explanation: The slope represents the gradient of a tangent of a curve at a given point on the curve.
Correct answer: With different sizes of triangles drawn- A. Speed
- B. Velocity
- C. Acceleration
- D. Momentum
Explanation: "Velocity" is defined as the rate of change of displacement. "Velocity" = Displacement / Time
Correct answer: Velocity69. The displacement of objects with respect to a constant moving (v) frame in the same direction is?
- A. x - vt
- B. x + vt
- C. x
- D. x + vt + at2.
Explanation: When an object moves at a constant speed in the same direction then the velocity is also constant and it will not change the speed and…
Correct answer: x + vt- A. car travels 20 km due east and car travels 70 km due west.
- B. car travels 40 km due east then turns around and travels 20 km due west and car travels 20 km due east
- C. car travels 40 km due east then turns around and travels 20 km due west and car travels 70 km due east
- D. car travels 30 km due west then turns around and travels 30 km due east and car travels 40 km due east, then turns around and travels 20 km due west
Explanation: Trip A displacement: 40 Km east then 20 km west, in vector form we can say that the car travels +40 then -20.
Correct answer: car travels 40 km due east then turns around and travels 20 km due west and car travels 20 km due east- A. dx/dt
- B. Δx/Δt
- C. Δx.Δt
- D. Δv/Δt
Explanation: The instantaneous velocity of a body is defined as the limit of the ratio of the change in position ∆d to the small interval ∆t as ∆t…
Correct answer: dx/dt- A. area under graph represent displacement
- B. gradient of the graph is constant
- C. gradient of the tangent of graph represents acceleration
- D. gradient of the tangent of graph represents velocity
Explanation: If displacement time graph is a curve then the gradient of the tangent of the graph represents velocity because v = x/t
Correct answer: gradient of the tangent of graph represents velocity- A. m/s
- B. 1/s
- C. m/s2
- D. m/s3
Explanation: Correct Option: A(unit) m/s is the SI unit of velocity.The SI unit of velocity is meters per second (m/s).
Correct answer: m/s- A. Linear
- B. Quadratic
- C. Cubic
- D. Decreasing linearly
Explanation: If the velocity of a particle is varying linearly with time, then the shape of the distance-time (d-t) curve would be a quadratic curve.
Correct answer: Quadratic- A. Distance is greater than displacement
- B. Distance is less than displacement
- C. Distance is equal to displacement
- D. There is not enough information available
Explanation: We cannot determine the relationship between distance and displacement by using information about speed.
Correct answer: There is not enough information available- A. Its displacement is constant
- B. Its displacement changes due to change in distance
- C. Its displacement changes due to change in direction of motion
- D. Its displacement is always zero
Explanation: At the end of each revolution, the object returns to the initial point. Therefore, the net displacement covered is zero.
Correct answer: Its displacement is always zero- A. Only its distance is zero.
- B. Only its displacement is zero.
- C. Neither distance nor displacement is zero.
- D. Both distance and displacement is zero.
Explanation: Correct option is B. When an object moves in a circular path and returns back to its initial position then only its displacement is zero.
