## FAQs on System of Particles & Rotational Motion in One Shot (NCERT) Video Lecture - Physics Class 11 - NEET

 1. What is the difference between linear motion and rotational motion?
Ans. Linear motion refers to the movement of an object in a straight line, while rotational motion refers to the movement of an object around an axis or a fixed point.
 2. How does the distribution of mass affect the rotational motion of an object?
Ans. The distribution of mass affects the rotational motion of an object by determining its moment of inertia. Objects with more mass concentrated towards their center have a smaller moment of inertia and rotate faster, while objects with mass spread out have a larger moment of inertia and rotate slower.
 3. What is the conservation of angular momentum?
Ans. The conservation of angular momentum states that the total angular momentum of a system remains constant unless acted upon by external torques. This means that if no external torques are applied, the angular momentum of a rotating system will remain constant.
 4. How can we calculate the moment of inertia of a system of particles?
Ans. The moment of inertia of a system of particles can be calculated by summing up the products of the mass of each particle and the square of its distance from the axis of rotation. Mathematically, it can be expressed as I = Σ(mr^2), where I is the moment of inertia, m is the mass of each particle, and r is the distance of each particle from the axis of rotation.
 5. What is the difference between torque and angular momentum?
Ans. Torque is the measure of the force that can cause an object to rotate around an axis, while angular momentum is the measure of an object's rotational motion. Torque depends on the force and the distance from the axis of rotation, while angular momentum depends on the moment of inertia and the angular velocity of the object.
