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 ...

Learn how to analyze tipping a block and calculating friction in this physics tutorial. Step-by-step explanations cover forces, torque, and frictional calculations, helping students understand the ...

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 ...

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

Today is the first day of second grade for SteelyKid, and yesterday I took her and her brother, The Pip, to the outdoor pool for an end-of-summer swim. While loading them into the car on the way home, ...
