I WONDER - Are There Different Types Of Friction?

The video tutorial explains different types of friction: dry, fluid, and rolling. Dry friction occurs between solid objects and is divided into static (when objects are not moving) and kinetic (when objects are moving). Fluid friction involves resistance from fluids like water or air. Rolling friction happens when a round object rolls over a surface, such as a ball or wheel.
