Question

What is the condition for pure rolling?

Answer 1

Pure rolling:

1. Pure rolling is the process of rolling in which no sliding is visible.
2. Pure rolling is a combination of translation and rotation motion in which the point of contact comes to rest instantly because there is no sliding.
3. The velocity $v$ of a rolling object is proportional to its angular velocity.
4. It can be expressed mathematically as $v=\omega R$, where $R$ is the radius of the object, $v$ is its linear velocity and $\omega$ is angular velocity.
