I WONDER - Are There Different Types Of Friction? Me Pregunto - Existen Diferentes Tipos De Fricción?

The video tutorial explains different types of friction: dry, fluid, and rolling. Dry friction is divided into static and kinetic friction, depending on whether the objects are stationary or in motion. Fluid friction involves resistance from fluids like water or air. Rolling friction occurs when a round object rolls over a surface, such as a ball or wheel.

Describe the conditions under which dry friction occurs.

What is rolling friction and when does it occur?
