Explore the fundamentals of motion with Exploring the Basics of Static and Kinetic Friction Forces in Physics. Learn how friction influences movement, the differences between static and kinetic ...

Say we consider a simple experiment of balancing a wooden rod on two fingers. The finger on the left, (1), will remain stationary, whereas the finger on the right, (2), will be moved toward the left.

Researchers have demonstrated how to entirely suppress static friction between two surfaces. This means that even a minuscule force suffices to set objects in motion. Especially in micromechanical ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...

Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that arises without any mechanical contact, driven purely by collective magnetic ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

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 ...

Many less-experienced users of finite-element-analysis (FEA) software often have no clue if the results they get are anywhere near the correct answer. To gain more confidence with FEA, it’s a good ...

Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, their internal forces compete, causing constant rearrangements that ...
