Write the meaning of homogeneous bodies.
What is system of particle ?
The variation of angular position $\theta $ of a point on a rotating rigid body with time t is shown in figure. Is the body rotating clockwise or anti-clockwise ?
Write the Newton's second law for rotational motion about a fixed axis.
A uniformly thick wheel with moment of inertia $I$ and radius $R$ is free to rotate about its centre of mass (see fig). A massless string is wrapped over its rim and two blocks of masses $\mathrm{m}_{1}$ and $\mathrm{m}_{2}\left(\mathrm{m}_{1}>\mathrm{m}_{2}\right)$ are attached to the ends of the string. The system is released from rest. The angular speed of the wheel when $\mathrm{m}_{1}$ descents by a distance $h$ is
What is rotational motion and axis ?
