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 ...

Avoid common pitfalls when calculating work done by friction! This video highlights the most frequent mistakes students make, from misinterpreting frictional forces to applying formulas incorrectly.

At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow. Scientists in Amsterdam have found that this same kind of behavior happens at a ...

For the first time, physicists in China have virtually eliminated the friction felt between two surfaces at scales visible to the naked eye. In demonstrating "structural superlubricity," the team, led ...

MIT scientists have coaxed atoms into an exotic “edge state” for the first time, allowing them to flow completely friction-free. The breakthrough could lead to better superconductor materials. As ...

When starting this ice challenge, most people just step on the side of the bowl and slide down to the bottom. Then you’re ...

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