Quick, out behind the bike shed, Professors Pendry and Leonhardt are having a fight over a completely hypothetical situation. If we hurry, we should catch the end of round three. Science: it is ...

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 ...

Solve the classic physics problem of equilibrium for a leaning ladder! This guide helps you understand how to calculate the forces acting on a ladder in equilibrium, considering friction, normal force ...

Humans have been making fire using friction for thousands of years, with evidence of its use found in archaeological records across different cultures worldwide. Fire by friction is a testament to ...

Here’s the rub with friction — scientists don’t really know how it works. Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of ...

Is friction real? Once, with the quiet certainty of someone who just stayed up all night in the company of equations describing concrete, my college roommate told me that friction was made up. Now, ...

Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects - particularly in wet ...

Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival. In the scramble to revolutionize the world with nanotechnology ...
