It’s perhaps the second week of your introductory physics course. Your instructor starts talking about friction and writes the following two formulas on the board. Then there is probably some ...

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.

When two surfaces rub against each other, why is there a friction force? The basic answer is that the stuff the two surfaces are made of (atoms) are interacting with each other. Skip to main content ...

Experiments often yield ignition temperatures in the range of 650-800 degrees Farenheit (340-430 degrees Celsius), with the most reliable estimates on the order of 700 degrees F (370 degrees C).

IIT Kanpur assistant professor Adhip Agarwala explains the physics of friction, its effects on various aspects of daily life in India, and how it can be reduced or eliminated.

"Friction is puzzling because it is not governed by a single interaction, like attraction between charges; it emerges from a combination of processes that can occur at different scales. In our work, ...
