## Types of friction

Air Resistance or Drag is the type of friction that a falling object encounters while in the air. It has three classifications which are the lift-induced, the parasitic drag.

We all slow down our vehicles whenever needed by applying brakes. Do you know why a vehicle slows down when brakes are applied? Not only vehicles any object moving on the surface of another object slows down and stops without any external force acting on it because of "friction". Before going to types of friction, lets know about friction. According to law of physics any object in the world can't be friction-less. Friction is a force that opposes the motion of two contacting surfaces.

Air resistance. No matter how much force These things are air resistance and friction. It happens because the surfaces kind of stick together a little. Before going to types of friction, lets know about friction. Viscosity is the measure of the resistance of the air to flow and it differs from one density another. The four types of friction and how they act on objects.

In fluid dynamics , drag sometimes called air resistance , a type of friction , or fluid resistance , another type of friction or fluid friction is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. Unlike other resistive forces, such as dry friction , which are nearly independent of velocity, drag forces depend on velocity. Even though the ultimate cause of a drag is viscous friction, the turbulent drag is independent of viscosity. Drag forces always decrease fluid velocity relative to the solid object in the fluid's path. Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the direction of movement of a solid object such as cars, aircraft [3] and boat hulls; or acting in the same geographical direction of motion as the solid, as for sails attached to a down wind sail boat, or in intermediate directions on a sail depending on points of sail. In the physics of sports, the drag force is necessary to explain the performance of runners, particularly of sprinters. The phrase parasitic drag is mainly used in aerodynamics, since for lifting wings, drag is generally small compared to lift.
