A wheel has an angular acceleration of rad/s2 and an initial angular speed of rad/s. In a time of s, it has rotated through an angle (in radians) of:
| 1. | 2. | ||
| 3. | 4. |
The torque on the wheel becomes zero at:
| 1. | s | 2. | s |
| 3. | s | 4. | s |
A solid sphere of mass and radius is rotating about its diameter. A solid cylinder of the same mass and the same radius is also rotating about its geometrical axis with an angular speed twice that of the sphere. The ratio of their kinetic energies of rotation (sphere/cylinder) will be:
| 1. | 2. | ||
| 3. | 4. |
Three objects, (a solid sphere), (a thin circular disk) and (a circular ring), each have the same mass and radius They all spin with the same angular speed about their own symmetry axes. The amount of work required to bring them to rest, would satisfy the relation:
| 1. | |
| 2. | |
| 3. | |
| 4. |

Preparing Rotational Motion Kinematics for NEET
Rotational Motion Kinematics is a specific sub-topic that frequently appears in the NEET examination. Understanding the underlying principles and practicing targeted questions is key to mastering this concept.
The questions compiled above are previous year questions (PYQs) directly related to Rotational Motion Kinematics. Practicing these specific questions helps you understand the difficulty level and the examiner's approach to this topic.
Topic Frequently Asked Questions
Is Rotational Motion Kinematics a high-weightage topic?
You can refer to the priority and consistency badges at the top of this page. High priority topics should be thoroughly revised multiple times before the exam.
Should I memorize the solutions?
No, it is highly recommended to understand the core concept and methodology behind each solution rather than memorizing them, as exact questions are rarely repeated, but the concepts definitely are.
