Friction is caused when two surfaces come into contact with one another. The irregularities on the surfaces rub against one another and friction results. Friction opposes motion. That is to say, friction acts in the direction opposite to motion.
Rolling friction is the force of friction between two surfaces when one surface rolls over another.Sliding friction is the force of friction between two surfaces when one surface is moving on another.
If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.
There are three types of friction, static friction, rolling friction, and sliding friction. Static friction is friction between two surfaces that aren't moving relatively to each other. Rolling friction is friction between a rolling object and the surface that it is rolling on. Sliding friction is friction where an object slides, or rubs against, another surface.
One way to tell if friction is happening is if there is heat. Friction occurs when two things rub against each other, and this generates heat. Another way to tell is if the items are becoming chafed.

Yes but make sure you are clear in your understanding between the coefficient of friction and the force of friction. The force of friction is the force that resists the motion of two surfaces moving against one another. The amount of friction is determined by the product of the coefficient of friction and the normal (perpendicular) force that is pressing the two surfaces together. The coefficient of friction is a unit-less constant, that indicates how two surfaces compare to two other surfaces that are being pressed together the same amount. If the normal force is the same on two pairs of surfaces the pair of surfaces with the lowest coefficient of friction will experience the lower force of friction.
one way to reduce friction between two surfaces is to add oil. oil fills in the gaps between surfaces , and keeps many of the high spots from making contact. because there are fewer contact points between the surfaces, the force of friction is reduced. more of the input work then is converted to output work by the machine.
Rolling friction is the force of friction between two surfaces when one surface rolls over another.Sliding friction is the force of friction between two surfaces when one surface is moving on another.

To reduce friction, which is a resistance between two surfaces in contact. The points of contact between moving parts in a machine create heat (which is actually a desired effect in a flintstone, in which one strikes a flintstone with another rock to create heat as a means of starting a fire) and cause damage in their grinding against one another. Oil reduces the friction, which reduces the heat generated and the damage from the moving part surfaces grinding against one another; this reduction in friction is called lubrication.

The force that acts whenever two surfaces or objects mass put past one another is friction
Friction refers to the resistance that one surface or object encounters when moving over another. The two common forms of friction between two sliding surfaces are static friction and rolling friction.
The increase in One increases the Other. What alters the friction effects between Surfaces is another matter.
