I don't normally watch many NASCAR races, but I do come across some NASCAR videos online. Sometimes these clips become the basis of a great physics problem. In this case, it's a 21-car crash at the ...
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 sort of ...

COLUMBUS, Ohio – An engineer at Ohio State University recently demonstrated the world's first method for directly measuring friction between tiny microelectromechanical-system (MEMS) parts. Using an ...
Friction is the force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult. Friction ...
