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 ...
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 ...
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 ...
In this video, we break down the concept of the coefficient of friction in AP Physics 1, explaining how static and kinetic friction work and how they affect motion. Clear examples and reasoning help ...
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 ...
In "Friction," tribologist Jennifer Vail shows how the fundamental force that resists motion keeps driving us forward.
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, ...
