Moment of Inertia of Disc about an axis passing through center and perpendicular to plane is the Derivation for IIT-JEE and NEET Physics that we are doing in this video lesson. Moment of inertia is to find out how much difficult or easy it is to put a body in rotational motion and what magnitude of torque is required to rotate the body. It depends on the mass of the body and the distance of particles from axis of rotation. That means it depends on size and shape of the body.
IIT-JEE and NEET Physics is is a Complete Physics Resource for preparing IIT-JEE,NEET,CBSE,ICSE and IGCSE. All Physics topics are divided into multiple sub topics and are explained in detail using concept videos and synopsis.Lots of problems in each topic are solved to understand the concepts clearly.
