Rolling & Dragging Friction (1830)

The conclusions drawn from the foregoing remarks are that the friction of a roller moving over a horizontal surface depends on the relation between the velocity of the periphery and that of the centre of gravity also that this relation between the tangential velocity and that of transportation will depend on the moment of inertia of the cylinder
