JEE MAINS || ADVANCED|| NEET || PHYSICS||A SYSTEM OF PARTICLES

Rolling motion combines pure rotational and pure translational motion. When a body rolls without slipping, it's considered pure rolling, where the point of contact remains stationary. This means it's moving forward (translation) while also spinning (rotation). Pure Translational Motion: Definition: Movement where all points on an object move the same way, along a straight line, without rotation. Example: A block sliding across a table. Pure Rotational Motion: Definition: Movement where all points on an object move in a circular path around a fixed axis. Example: A wheel turning around a fixed axle. Rolling Motion (Combination): Definition: A combination of both pure translation and pure rotation. In pure rolling (without slipping): The point of contact between the rolling object and the surface is momentarily at rest, meaning it's not sliding. Example: A wheel rolling across a road without skidding. Key Points about Rolling Motion: Translation: The motion of the center of mass of the rolling object. Rotation: The spinning motion around an axis that is moving along with the object. No Slipping: In pure rolling, there's no sliding at the point of contact.
