Webfriction is important: 1. Flow of fluid in a circular pipe, 2. Slow linear motion of objects through a fluid. 3. Levitation by an air jet. The first two are examples of viscous drag, while the third emphasizes high-speed drag. Viscous Drag Quantitative consideration of friction in fluids began with Newton, whose original ex- WebLaws of motion Static friction Frictional force between surfaces which are at rest relative to each other is called static frictional force. Static frictional force is directly proportional to the normal reaction Static frictional force depends on the nature of surfaces in contact.

WebFriction When we throw a ball on the floor, it starts moving with some velocity. But ideally, no force should be acting in the direction of motion, and according to Newton’s first law, the ball should keep rolling, but this does not happen. Instead, the ball stops after moving a certain distance, so a force must be acting on it. WebIntroduction to Tribology – Friction . The science of Tribology (Greek tribos: rubbing) concentrates on Contact Mechanics of Moving Interfaces that generally involve energy dissipation. It encompasses the science fields of Adhesion, Friction, Lubrication and Wear.. Leonardo da Vinci (1452-1519)) can be named as the father of modern tribology. He …
