ANSWER:Solution: Friction most commonly refers to the resisting force generated when two solid surfaces slide against one another. However, there is actually a wide variety of different types of friction that includes skin friction, fluid friction, internal friction, lubricated friction and dry friction. Each of these frictional energies has unique features and dynamics, but the overarching hallmarks of frictional forces remain the same. When two touching surfaces slide against one another, complex interactions occur at an electromagnetic level between the surface's charged particles. These friction
