There are four types of friction: static, sliding, rolling, and fluid friction (Air/Viscous friction). Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases. https://www.careerlauncher.com › C...

Friction is a force that opposes the relative motion between two surfaces of ... Related searches • Friction: A force that opposes motion between two objects that are in contact with each other. Smoother surfaces exhibit less friction, rougher surfaces exhibit more friction. • Friction opposes the relative motion between two surfaces in contact. It acts on both the surfaces. • Friction depends on the nature of surfaces in contact. • Types of Friction: (i) Static Friction: When a body is at rest, the force of friction is called the static friction and is always equal and opposite to the applied force. The force of friction which acts when the body is just at the verge of sliding on the surface is called limiting friction. (ii) Sliding friction: The friction force which opposes the actual relative sliding motion between two contact surfaces. Sliding friction is smaller than static friction. (iii) Rolling Friction: The frictional force that exists between two surfaces when a body rolls over the other. Rolling friction is smaller than sliding friction. • Increasing Friction: By pressing the surfaces together more strongly. When brakes are applied on a bicycle or car, the brake pads press against a moving part of the wheel and the force of friction increases. • Reducing Friction: Polishing, Lubricating, using ball bearings, separation of surfaces by air, streamlined shape. • Causes of friction: Friction is caused by the irregularities on the two surfaces in contact. Even those surfaces which appear very smooth have a large number of minute irregularities on them. • For a given pair of surfaces friction depends upon the state of smoothness of those surfaces. • Friction depends on how hard the two surfaces
