Q. A uniform circular disc of radius r rolls without slipping with a constant velocity on a stationary horizontal surface. Find the distance covered by a point P on its circumference in one full rotation.

Q. Assertion :A rigid disc rolls without slipping on a fixed rough horizontal surface with uniform angular velocity. Then the acceleration of lowest point on the disc is zero. Reason: For a rigid disc rolling without slipping on a fixed rough horizontal surface, the velocity of the lowest point on the disc is always zero.

Statement 1:

A rigid disc rolls without slipping on a fixed rough horizontal surface with uniform angular velocity, then the acceleration of the lowest point on the disc is zero.

Statement 2:

For a rigid rolling without slipping on a fixed rough horizontal surface, the velocity at the lowest point on the disc is always zero.

Q. Statement-1: A rigid disc rolls without slipping on a fixed rough horizontal surface with uniform angular velocity. Then the acceleration of lowest point on the disc is zero.
