Traction Surface Friction Moving Thing Move Slipping Spinning

word traction
definition The friction that allows a moving thing to move over a surface without slipping.
eg_sentence The spinning wheels were getting no traction on the ice, and we began to slip backward down the hill.
explanation A tractor is something that pulls something else. We usually use the word for a piece of farm machinery, but it's also the name of the part of a big truck that includes the engine and the cab. Tractors get terrific traction, because of their powerful engines and the deep ridges on their huge wheels. A cross-country skier needs traction to kick herself forward, but doesn't want it to slow her down when she's gliding, so the bottom of the skis may have a “fish-scale” surface that permits both of these at the same time.
