WebbNote that μ k is not strictly a constant, but this empirical rule is a good approximation for finding frictional forces. Values given for the coefficients of static and kinetic friction do vary with speed and surface conditions so that it is not necessarily true that static friction exceeds sliding friction.

WebbStatic friction prevents sliding. Static friction is the force holding an object in place on an incline, such as the cheese in Figure 1. The friction force points against the direction that the object would slide without friction. Static friction keeps gravity from pulling the cheese down the incline. WebbPHYSICS 151 – Notes for Online Lecture #12 Friction: The basic facts of macroscopic (everyday) friction are: 1) Frictional forces depend on the two materials that are sliding past each other. A box sliding over a waxed floor experiences less friction than a box sliding over an unwaxed floor.

Friction is that force which opposes the motion of two objects upon each other. Friction generates only when two objects are in contact with each other. When an object tries to move on other objects than an opposing force develops and resist this movement known as Friction. The friction force is likely to terminate the movement if …
