Schematic illustration of Friction Force Microscopy (FFM). The AFM cantilever, a small diving board-like structure about 200 micrometers long, 50 micrometers wide, and 1 micrometer thick, has a sharp ...

Learn how to calculate the coefficient of friction on inclined planes in this physics tutorial. Step-by-step explanations cover the forces, equations, and reasoning you need to solve friction problems ...

Explore how forces and friction work to hold a block against a vertical wall. This video explains normal force, frictional force, and equilibrium conditions, showing how these forces balance to ...

Here’s the rub with friction — scientists don’t really know how it works. Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of ...

The term tribology is derived from the Greek word "tribo" meaning rubbing and "logy" meaning knowledge. The original applications by the Greeks of tribology were in trying to understand the motion of ...

This is a cooler physics problem than I initially realized. It goes something like this. A block has a mass of 1 kg and is placed on a vertical wall such that the coefficient of static friction is 0.5 ...

How much do you know about friction? Jennifer R. Vail's charming, if sometimes technical, "biography" of the force showcases its amazing and largely overlooked role in everything from climate change ...

Of course, the study of friction is nothing new; and to explain the 20th-century crisis, and to understand where tribology ...
