Rotating wheel angular momentum || Rotational motion

The following motion is based on the law of conservation of angular momentum (A) rotation of top (B) diving of driver (C) rotation of ballet dancer on smooth horizontal surface (D) a solid sphere that rolls down on an inclined plane

A rigid body rotates with an angular momentum L. If its rotational kinetic energy is made 4 times, its angular momentum will become

A body is rotating with angular momentum L. If I is its moment of inertia about the axis of rotation is I, its kinetic energy of rotation is

Rotational Motion - Angular Momentum

Direction of angular momentum of rotating body in vertical plane is

Calculate the angular momentum of a body whose rotational energy is 10 joule. If the angular momentum vector coincides with the axis of rotation and its moment of inertia about this axis is 8xx10^(-7) kg m^(2)

The law of conservation of angular momentum is obtained from Newton's II law in rotational motion when

A hollow sphere and solid sphere of the same radius rotate about their diameters with the same angular velocity and angular momentum. Then the ratio of their masses is
