Rotational Dynamics and Oscillatory Motion Complete Notes:
Rigid body: A body is which the distances between particles is fixed irrespective to its motion (rotational or translational) is called rigid body. In nature a perfect rigid body doesn’t exist, however a solid is consider as a rigid body.
A rigid body consists of number of Constraints between particles within it.
