Friction: Crash Course Physics
Why is it hard to move a heavy bookcase across a carpeted floor? And why is it easier to keep it moving than it was to get it started moving? You might think it's all about weight, but actually it's about friction. Two kinds of friction!...

Why Is Static Friction Greater Than Kinetic Friction?
Friction is the resistance that one object or surface experiences when moving over another object or surface. The two types of friction that come into play when moving two objects against one another are static and kinetic. Static...

Separating Notebooks
We interleave the pages of notebooks to see how hard it is to pull them apart. As the amount of interleaving increases, we see that the force required to separate them also increases. This is because the friction between the notebooks is...
