Most people have experienced the hair-raising effect of rubbing a balloon on their head or the subtle spark caused by dragging socked feet across the carpet. Although these experiences are common, a ...

In today's episode, Shini tells us about Static and Kinetic friction. Why is it hard to move a heavy bookcase across a carpeted floor? And why is it easier to keep it moving than it was to get it ...

If you want to know how to make a sneaker with better traction, just ask a snake. That's the theory driving new research by an expert who is studying snake skin to help engineers improve the design of ...

Friction is a pervasive nonlinearity in mechanical systems, arising at interfaces from the microscale asperities of surfaces and manifesting in macroscopic performance degradation, wear and control ...

Scientists developed a new model, which shows that rubbing two objects together produces static electricity, or triboelectricity, by bending the tiny protrusions on the surface of materials. Most ...
