What you learn in Theory:
Rolling is a type of motion that combines rotation (commonly, of an axially symmetric object) and translation of that object with respect to a surface (either one or the other moves), such that, if ideal conditions exist, the two are in contact with each other without sliding.
What you learn in Practice:
Rolling is achieved by a rotational speed at the line or point of contact which is equal to the translational speed.
