Answer:
There are 4 types: Static Friction, Sliding Friction, Rolling Friction, Fluid Friction
Step-by-step explanation:
Static: frictional force that acts between the surfaces when they are at rest with respect to each other.
Ex: Skiing against the snow
Creating heat by rubbing both the hands together
Sliding: defined as the resistance that is created between any two objects when they are sliding against each other.
Ex: Sliding of the block across the floor
Two cards sliding against each other in a deck
Rolling: defined as the force which resists the motion of a ball or wheel and is the weakest types of friction.
Ex: Rolling of the log on the ground
Wheels of the moving vehicles
Fluid: defined as the friction that exists between the layers of the fluid when they are moving relative to each other.
Ex: The flow of ink in pens
Swimming
