Explore the physics behind a penny on a spinning record player and the role of friction! 🌀💡 In this video, we break down the forces acting on the penny, explain how friction affects motion, and ...

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 ...

In this video, we explain the capstan equation and how friction affects a rope or string wrapped around a surface. You’ll learn where the equation comes from, what each term means, and how it’s ...

It makes sense to think that reducing the friction in an engine, transmission, axle, and transfer case, will result in more power available to the wheels. While correct in theory, several industry ...

Graphene has been the subject of widespread research, in large part because of its unique combination of strength, electrical conductivity, and chemical stability. But despite many years of study, ...

Whenever you are trying to design a micromechanical system, it is likely to include the fundamental machine parts of gears, gimbals, hinges, pistons and suspended beams that flex. Brian Borovsky, ...
