Friction
Haley Albertson
Static friction
Is the type of friction when the object is NOT moving.
Rolling Friction
Is the type of friction that is rolling across a smooth surface. For example a ball rolling across the table.
Sliding Friction
Is the type of friction when a object is sliding across a smooth surface. For example, sliding a book across the table
Fluid Friction
Fluid friction is the force that resists the movement of a solid object through a fluid (liquid or gas). Sky divers falling down through the sky experience a type of fluid friction called air resistance
