Traction
Definition:
(n.) The act of drawing, or the state of being drawn; as, the traction of a muscle.
(n.) Specifically, the act of drawing a body along a plane by motive power, as the drawing of a carriage by men or horses, the towing of a boat by a tug.
(n.) Attraction; a drawing toward.
(n.) The adhesive friction of a wheel on a rail, a rope on a pulley, or the like.
