Most Repeated MDCAT Physics: Circular Motion & Momentum MCQs
The most repeated Circular Motion & Momentum questions in MDCAT Physics, measured from 377 real past papers. Circular Motion & Momentum contributed 387 questions across those papers, and 8 distinct questions recurred with the same verified answer across 2 or more different exam years — listed below (ranked by how many years each recurs in), with the answer, an explanation, and the exact years.

Why Circular Motion & Momentum is a high-yield MDCAT Physics topic
Out of 387 real Physics questions attributed to Circular Motion & Momentum across 377 MDCAT past papers, 8 distinct questions came back with the same correct answer in 2 or more different exam years (the recurrences here span 2009–2024, 10 distinct exam years). A question the examiners have reused verbatim is far more likely to appear again than one asked only once — which is exactly why working through this list first is one of the highest-return ways to revise MDCAT Physics. 1 of them recurred in 3 or more separate years.

“The physical quantity which produces angular acceleration in the body is”
Appeared in 3 exam years (2010, 2011, 2014) — always with the same answer. It is the first question below.
How to use this list
Every question below shows the verified correct answer, a short explanation, and the exact past-paper years it appeared in — with the most-repeated ones first. Read the explanation even when you know the answer, since MDCAT often reuses the concept with reworded options. When you have these 8 down cold, drill the full topic with fresh questions in the MDCAT MCQ practice bank.
How we measured “most repeated”
We parsed 377 real MDCAT past papers and grouped questions that are effectively the same. A question counts as repeated only when the same correct answer recurs in 2 or more distinct exam years — not merely a similar topic or a lucky guess. Questions that appeared only once are excluded, so nothing here is padding. See the full method and subject-by-subject numbers on the MDCAT repetition study.

The physical quantity which produces angular acceleration in the body is
- AForce
- BMoment of inertia
- CImpulse
- DTorque✓
Explanation
Torque is a measure of the force that can cause an object to rotate about an axis.

If the body is rotating with uniform angular velocity, then its torque is:
- AZero✓
- BClockwise
- CMaximum
- DRemains the same
Explanation
Explanation:If the body is rotating with uniform angular velocity, its angular momentum remains constant, and therefore there is no change in its rotational motion. Since torque is the rate of change of angular momentum, the torque acting on the body is zero. This option is not correct because if there is a clockwise torque acting on the body, it will cause the angular velocity to change, which is not the case when the body is rotating with uniform angular velocity.

A body having translatory motion possesses _ and _. In the same way a body having rotatory motion possesses _ and _.
- ANone of them
- BLinear velocity... Linear momentum... Angular velocity... Angular momentum✓
- CLinear momentum... Angular momentum... Linear velocity... Angular velocity
- DAngular velocity... Angular momentum... Linear momentum... Linear velocity
Explanation
The correct answer is: Linear velocity... Linear momentum... Angular velocity... Angular momentum.In translatory motion, all points of a body move uniformly in a single direction, involving linear properties such as linear velocity and linear momentum. This type of motion does not change the orientation of the object.In contrast, rotatory motion occurs when a body rotates around its own axis, involving angular properties like angular velocity and angular momentum. For example, the Earth's rotation about its axis is a type of rotatory motion.All options except B do not properly align the motion types with their respective properties, which is why they are incorrect.

Which of the following results in the centripetal acceleration being produced in a body?
- AChange in magnitude of velocity
- Bchange in mass
- CChange in magnitude of force
- DChange in direction of velocity✓
Explanation
When a body travels on a circular path, its direction constantly changes and thus its velocity changes, producing an acceleration. Hence option D is correct.

A wheel of a bike rotates from rest and achieves 6.28 radians/sec in 2 seconds. What will be its angular acceleration?
- A1 rad/sec2
- B1.5 rad/sec2
- C3.14 rad/sec2✓
- D6.28 rad/sec2
Explanation
As w = 6.28 rad/sec t = 2 sec α = w/t = 6.28/2 α = 3.14 rad/sec^2 Hence, option C is correct.

The ratio between linear velocity and radius equals to:
- AAngular displacement
- BAngular velocity✓
- CAngular acceleration
- DAngular momentum
Explanation
As v = r × w v/r = w Hence, the relation between linear velocity and radius is equal to angular velocity.

The moment of inertia of an object does not depend upon:
- AMass of an object
- BMass of distribution
- CAngular velocity✓
- DAxis of rotation
Explanation
The moment of inertia Iof an object is a measure of its resistance to changes in angular velocity. It depends on the mass of the object and how that mass is distributed around the axis of rotation, but it is not influenced by the current angular velocity. Therefore, option c is correct.

Which one of the following provides centripetal force in a circular motion of the body?
- AVertical component of weight
- BHorizontal component of weight
- CWeight of the body
- DForce of friction✓
Explanation
In circular motion (like a car turning on a flat road), the centripetal force that keeps the body moving in a circle is provided by the horizontal force directed towards the center. On a flat surface, this force is the force of friction between the tires and the road.
