FAQs on L 28 Rotational Motion- Heavy pulley ,Class 11 ,Physics Video Lecture - Additional Study Material for NEET

1. How does the mass of a pulley affect its rotational motion?
Ans. The mass of a pulley affects its rotational motion by changing its moment of inertia. A heavier pulley will have a larger moment of inertia, which means that it will be more resistant to changes in its rotational motion. This means that it will take more force or torque to accelerate or decelerate a heavy pulley compared to a lighter one.
2. What is the significance of the heavy pulley in rotational motion?
Ans. A heavy pulley has a significant impact on rotational motion because it increases the system's overall inertia. This increased inertia results in a slower rate of acceleration or deceleration of the pulley when subjected to an external force or torque. Therefore, a heavy pulley can affect the dynamics of the entire system, including the other objects connected to it.
3. How does the radius of a heavy pulley affect its rotational motion?
Ans. The radius of a heavy pulley affects its rotational motion by determining its moment of inertia. The moment of inertia of a pulley is directly proportional to the square of its radius. Therefore, a pulley with a larger radius will have a larger moment of inertia, making it more resistant to changes in rotational motion. This means that a heavy pulley with a larger radius will require more force or torque to accelerate or decelerate compared to a pulley with a smaller radius.
4. Can a heavy pulley experience angular acceleration?
Ans. Yes, a heavy pulley can experience angular acceleration. Although a heavy pulley has a larger moment of inertia and is more resistant to changes in rotational motion, it can still undergo angular acceleration when subjected to a net torque. The magnitude of the angular acceleration will depend on the magnitude of the net torque applied to the pulley and its moment of inertia.
5. Does the mass distribution of a heavy pulley affect its rotational motion?
Ans. Yes, the mass distribution of a heavy pulley can affect its rotational motion. If the mass distribution is not uniform, the moment of inertia will vary at different points along the pulley's radius. This can result in uneven rotational motion and affect the system's overall dynamics. Therefore, it is important to consider the mass distribution when analyzing the rotational motion of a heavy pulley.
