As we know that the three equation of a linear motion are Where, the symbols have their usual meaning. In the similar way, we can write equations of motion for rotational motion such as Where, θ₀ and ω₀ are the initial angular displacement and initial angular velocity of the body, respectively.

Theorem Of Perpendicular Axis It state that the moment of inertia of a planner body about an axis perpendicular to its plane is equal to the sum of its moments of inertia about two perpendicular axis concurrent with perpendicular axis and lying in the plane of the body. Proof:- From the definition of moment of
The radius of gyration of a body about its axis of rotation may be define as the distance from the axis of rotation at which, if the whole mass of the body were concentrated, its moment of inertia about the given axis would be the same as with the actual distribution of mass. When the
The property of a body by virtue of which, it opposes the torque tending to change its state of rest or of uniform rotation about an axis is called rotational inertia or moment of inertia. Let a rigid body rotating with uniform angular velocity ω about a vertical axis through O. Let the body consists

If a body is supported on a point such that total gravitational torque about this point is zero, then this point is called centre of gravity of the body.
