Physics Notes Class 11 CHAPTER 7 SYSTEM OF PARTICLES AND ROTATIONAL MOTION Centre of Mass Centre of mass of a system is the point that behaves as whole mass of the system is Moment of Inertia The inertia of rotational motion is called moment of inertia. It is denoted by L The moment of inertia (I) of a body is a measure of its rotational inertia, that is, its resistance to change in its angular velocity.It depends on the location of the axis, that is, on how the mass of the body is distributed relative to the axis. Thus, a body does not posses a unique moment of inertia; different axes through the body are associated with different moments of inertia Moment of inertia about a given axis of rotation resists a change in its rotational motion; it can be regarded as a measure of rotational inertia of the body. It is a measure of the way in which different parts of the body are distributed at different distances from the axis The topics extensively covered in the notes of physics class 11 chapter 7 are: Centre of mass and its motion. Centre of mass of a 2 particle system, rigid body and a uniform rod. Momentum of force and momentum conservation. Torque. Moment of Inertia. Angular momentum and laws of conservation of momentum.
