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 ...

Sometimes you think you have a complete understanding of something and then BOOM—a simple problem throws everything out the window. Let's consider a very basic physics problem involving pushing a ...

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.

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...

COLUMBUS, Ohio – An engineer at Ohio State University recently demonstrated the world's first method for directly measuring friction between tiny microelectromechanical-system (MEMS) parts. Using an ...
