various types.

The friction or drag force, is used to analyze and determine the potential movement between the contact surfaces of two bodies. In particular, the force that resists the movement, and consists of various types. The guy who people are probably familiar with dry friction is called – in contrast to fluid friction, the friction of the skin and internal friction. Dry friction is divided into static friction and kinetic friction.

Static friction and kinetic friction

The name pretty much says it all, but here is a basic overview for good measure. Static friction is the frictional force that opposes motion between the permanent members, or organizations that do not move to another. The force of friction between the tire and rubber flooring that allows a vehicle to accelerate is a good example of static friction.

This can be confused with the kinetic friction due to the fact that the tires and vehicles are in motion. However, due to the special section of rubber in contact with the ground is stationary relative to the ground, is the static friction. If not for the force of static friction, the vehicle would not be able to accelerate – at least not quickly.

A good example of kinetic friction is when you press the brake when traveling at high speed, lock the wheels to skid on the road. From the point of the rubber tire begins to slip is the point of releasing the brakes or make a complete stop, experience kinetic friction.

The coefficient of friction and traction COF

Traction is another way of describing the maximum static friction before the move or slip. However, to determine the coefficient of static friction drive (COF) between the two bodies in question is necessary.

The friction coefficient is the ratio of the friction force between two bodies and the normal force or the force that is pushing them together – equal to the weight force of the upper of the two bodies. There are two types of friction: the coefficient of static friction and kinetic friction. The coefficient of static friction is generally greater than kinetic friction.
