rolling friction

noun

1. engineering frictional resistance to rotation or energy losses in rolling bearings Compare sliding friction

Example Sentences

And overinflating your tires will reduce rolling friction and improve your mileage a bit.

From Seattle Times

Friction of solids may be divided into two classes: sliding friction, such as exists between the piston and cylinder, or the bearings of a gas-engine, and rolling friction, which is that present when the load is supported by ball or roller bearings, or that which exists between the tires or the driving wheels and the road.

From Project Gutenberg

And when you had casters put to the legs of the table, in order to move it more easily, you changed the rubbing into the rolling friction.

From Project Gutenberg

That is to say, by converting the rolling friction into the rubbing friction.

From Project Gutenberg

Two years later, with a dynamometer which he designed for the purpose, he made experimental determinations of the resistance of trains, and showed that it was made up of several kinds, as the sliding friction of the axle-journals in their bearings, the rolling friction of the wheels on the rails, the resistance due to gravity on gradients, and that due to the resistance of the air.
