Free Angular Velocity MCQs with Answers
105 Angular 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.
Angular velocity describes how quickly angular displacement changes with time, with ω = Δθ/Δt and units of radians per second. Questions relate angular and linear motion through v = rω, use the direction given by the right hand rule, and distinguish angular velocity from angular acceleration and ordinary frequency.

- A. 5 radians per second
- B. 31.4 radians per second
- C. 300 radians per second
- D. 1885 radians per second
Explanation: 300 revolutions per minute is 5 revolutions per second, and each revolution is 2 pi radians, so omega is 5 times 2 pi, which is 31.4…
Correct answer: 31.4 radians per second- A. has zero acceleration
- B. is accelerating, because the direction of its velocity is continuously changing
- C. has a constant velocity
- D. experiences no net force
Explanation: Velocity is a vector, so changing its direction is a change in velocity even when the magnitude is fixed, and that change per unit time is…
Correct answer: is accelerating, because the direction of its velocity is continuously changing- A. a real force acting outwards on the passenger
- B. the reaction to the passenger's weight
- C. an apparent force arising because the passenger is in a rotating, non inertial frame
- D. always larger than the centripetal force
Explanation: In the ground frame the passenger simply continues in a straight line by inertia while the bus turns beneath them, so no outward force is…
Correct answer: an apparent force arising because the passenger is in a rotating, non inertial frame- A. T equals omega over 2 pi
- B. T equals 2 pi omega
- C. T equals 2 pi over omega
- D. T equals omega squared
Explanation: One complete revolution covers 2 pi radians, so the time taken is 2 pi divided by the angular speed.
Correct answer: T equals 2 pi over omega- A. its mass only
- B. its mass and how that mass is distributed about the axis of rotation
- C. its angular speed
- D. the torque applied to it
Explanation: Moment of inertia is the sum of each mass element multiplied by the square of its distance from the axis, so moving mass further out…
Correct answer: its mass and how that mass is distributed about the axis of rotation- A. the angular speed increases, because the moment of inertia decreases and angular momentum is conserved
- B. the angular speed decreases
- C. the angular momentum increases
- D. nothing changes
Explanation: With no external torque the angular momentum, the product of moment of inertia and angular speed, stays constant, so reducing the moment…
Correct answer: the angular speed increases, because the moment of inertia decreases and angular momentum is conserved- A. I alpha
- B. I omega
- C. m v r squared
- D. half I omega squared
Explanation: Angular momentum is the moment of inertia multiplied by the angular speed, the rotational analogue of linear momentum mv.
Correct answer: I omega- A. half m v squared
- B. I omega
- C. half I omega squared
- D. I alpha
Explanation: Replacing mass with moment of inertia and linear speed with angular speed in the familiar expression gives half I omega squared.
Correct answer: half I omega squared- A. π
- B. 3π
- C. 6π
- D. 12π

- B. 5 rad. S-1
- C. 1.6 rad. S-1
- D. 2.8 ms-1

- B. Each point on its rim moves with constant acceleration
- C. The angle through which the wheel turns in each second decreases as time goes on.
- D. The wheel turns through equal angles in equal times.
Explanation: When a wheel turns with constant angular speed, each point on its rim travels through the same angle in equal intervals of time.
