Friction plays a key role in how ruptures unzip faults in the Earth’s crust and release waves that cause destructive shaking. Yet dynamic friction evolution is one of the biggest uncertainties in ...

A new analysis of the 2018 collapse of Kilauea volcano's caldera helps to confirm the reigning scientific paradigm for how friction works on earthquake faults. The model quantifies the conditions ...

Introduction Have you ever driven up a mountain, seen a sign reading "Hazard! Icy Roads Ahead," and wondered why ice makes roads dangerous to drive on? The answer has to do with friction—specifically, ...

Friction is the force between two surfaces that are trying to slide across each other. Friction always slows down a moving object. The amount of friction depends on the material the two objects are ...

In this Hub Lab with Phil of Science we are looking at friction. Friction is a force that resists motion, think of it as a force that slows things down. Friction is the reason you can slip around on ...

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 ...
