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.

Learn how to analyze tipping a block and calculating friction in this physics tutorial. Step-by-step explanations cover forces, torque, and frictional calculations, helping students understand the ...

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 ...

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 ...

Physicists directly observed ultracold atoms in an 'edge state,' flowing along a boundary without resistance. The research could help physicists manipulate electrons to flow without friction in ...

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