Learn how to calculate the coefficient of friction on inclined planes in this physics tutorial. Step-by-step explanations cover the forces, equations, and reasoning you need to solve friction problems ...

Sometimes you think you have a complete understanding of something and then BOOM—a simple problem throws everything out the window. Let's consider a very basic physics problem involving pushing a ...

Really, this is the experiment I wanted to start on. How does friction work in Bad Piggies? Let me start with a quick summary of my experiments so far. Scale. For the size of stuff in Bad Piggies, I ...

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 ...

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 ...

One of the dirty little secrets of physics is that there is no generally accepted explanation of the basic laws of friction. An advance in the theory of cracks will stimulate fresh thinking on the ...

Of course, the study of friction is nothing new; and to explain the 20th-century crisis, and to understand where tribology ...
