Q. In pure rolling motion, the point of contact with the ground has what type of velocity relative to the ground?
शुद्ध रोलिंग गति में, जमीन के संपर्क बिंदु पर जमीन के सापेक्ष किस प्रकार का वेग होता है?
Explanation
In pure rolling, the point of the rolling object in contact with the ground is instantaneously at rest relative to the ground. This is because the translational velocity of the center of mass is exactly canceled by the rotational velocity at the point of contact.
