Learn how to solve a ladder friction problem and determine the minimum coefficient of friction. Step-by-step explanations make it easy to understand the physics behind ladder stability and forces in ...

In "Friction," tribologist Jennifer Vail shows how the fundamental force that resists motion keeps driving us forward.

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 ...
