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 ...

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 ...

In modern physics, gravity is no longer understood as a force pulling objects together. It is the bending of spacetime itself ...

In "Friction," tribologist Jennifer Vail shows how the fundamental force that resists motion keeps driving us forward.

The ice in a domestic freezer is remarkably different from the single crystals that form in snow clouds, or even those formed ...

I learned to respect friction, as a phenomenon with many nuances, when I was a graduate student. One day, while teaching a problem session in elementary mechanics, I unwisely invented a new problem to ...

Innovation flourishes not because people collaborate more broadly but because the right people fall into productive orbit ...

Shawn Frayne’s Windbelt uses vibrating ribbons, not blades, to harvest wind efficiently on a smaller scale where traditional turbines fail completely now.
