A sphere is rotating about a diameter
The particles on the surface of the sphere do not have any linear acceleration
The particles on the diameter mentioned above do not have any linear acceleration
Different particles on the surface have different angular speeds
All the particles on the surface have same linear speed
Difference between rigid body and solid body.
What is pure translational motion ?
In motion of spinning top at any one place, whether the point in spinning top remains stationary or line remains stationary?
Write the Newton's second law for rotational motion about a fixed axis.
In the following figure, a body of mass $m$ is tied at one end of a light string and this string is wrapped around the solid cylinder of mass $M$ and radius $R$. At the moment $t = 0$ the system starts moving. If the friction is negligible, angular velocity at time $t$ would be
