Types of frictional forces with examples

I cover four types of friction. Static, fluid, kinetic, and rolling.
Static friction in which two surfaces are not moving past each other.
Sliding or Kinetic friction where 2 surfaces slide past one another.
Rolling friction between a rolling object and surface it rolls on.
Fluid friction is friction that occurs when objects move across or through a fluid.
