FAQs on Ace JEE Main 2025-26 with Rotational Motion Mock Tests

1. What is rotational motion?

Rotational motion refers to the movement of an object around a fixed axis or a central point. In this motion, all points of the object move along circular paths with their centers lying on the same straight line called the axis of rotation. Examples include the spinning of a wheel or the Earth's rotation about its axis.

2. What is the difference between rotational motion and circular motion?

While both rotational and circular motion involve movement along a circular path, rotational motion refers to the turning of an entire object about its own axis, whereas circular motion refers to an object or particle moving along the circumference of a circle, not necessarily about its own axis. For example, a fan blade spinning represents rotational motion, while a car turning around a roundabout exhibits circular motion.

3. Define moment of inertia and its significance in rotational dynamics.

The moment of inertia (I) is the measure of an object's resistance to changes in its rotational motion about an axis. It depends on the mass of the object and its distance from the axis of rotation. Higher moment of inertia means it is harder to rotate the object. It plays a role similar to mass in linear motion for rotational dynamics.

4. What are the equations of motion for rotational motion?

The basic equations of rotational motion are similar to linear equations, with angular analogs:
Angular displacement (θ)
Angular velocity (ω)
Angular acceleration (α)
The equations are:
1. ω = ω₀ + αt
2. θ = ω₀t + ½αt²
3. ω² = ω₀² + 2αθ
where ω₀ is initial angular velocity, t is time, and θ is angular displacement.

5. How is torque related to rotational motion?

Torque is the measure of the force that causes an object to rotate around an axis. It is calculated as the product of force and the perpendicular distance from the axis of rotation (τ = F × r). Torque is analogous to force in linear motion and is essential in changing the rotational state of an object.

6. What is the role of angular momentum in rotational dynamics?

Angular momentum (L) is the rotational equivalent of linear momentum. It is given by L = Iω, where I is the moment of inertia and ω is the angular velocity. In the absence of external torque, angular momentum remains conserved, meaning the rotational motion of the system will not change.

7. Can you explain the concept of rolling motion with examples?

Rolling motion is a combination of both rotational and translational motion, seen when an object such as a wheel or a cylinder moves forward while spinning. Examples include a ball rolling on the ground or wheels of a moving bicycle. In pure rolling, the point of contact with the surface has zero velocity relative to the surface.

8. What is the radius of gyration?

The radius of gyration (k) is the distance from the axis of rotation at which the entire mass of the body can be assumed to be concentrated, so that the moment of inertia remains unchanged. It is calculated as k = √(I/M), where I is the moment of inertia and M is the total mass of the object.

9. How does centripetal force affect objects in circular motion?

Centripetal force is the net force acting towards the center of the circle that keeps an object in circular motion. Without centripetal force, an object would move in a straight line due to inertia. In a rotating system, friction, tension, or gravity can provide the necessary centripetal force depending on the context.

10. What types of questions can be expected in JEE or MHT CET on rotational dynamics?

In JEE or MHT CET exams, students can expect questions on topics such as:
• Calculating moment of inertia of various bodies
• Problems on rotational kinematics and dynamics
• Torque and angular momentum
• Conservation of angular momentum
• Rolling motion and friction in rotational systems
• Conceptual MCQs on rotational and circular motion

11. Give two real-life examples of rotational motion.

Examples of rotational motion include:
• The spinning of a ceiling fan about its fixed axis
• The rotation of Earth around its own axis, leading to day and night.

12. What is the work-energy theorem for rotational motion?

The work-energy theorem for rotational motion states that the work done by external torques in rotating an object equals the change in its rotational kinetic energy. The equation is:
Work = ΔK.E. = ½I(ω² – ω₀²)
where I is moment of inertia, ω₀ is initial angular velocity, and ω is final angular velocity.
