Of friction is used to represent the degree to which two surfaces will resist sliding against one another.?
Coefficient~Apex:)
What is the cause of frictionand in what direction does it act with respect to the motion of sliding object?
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.
Why rolling friction is less than sliding friction?
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.
What is the friction that exits between a surface sliding on another surface is called?
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.
What are the three types of friction and when does each apply?
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.

A lower coefficient of friction indicates that the two surfaces in contact have less resistance?
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.
How friction reduces the efficiency of machines.?
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.
Why rolling friction is less than sliding friction?
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.

Why do you put oil in a machine?
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.
How do you know when something represent friction?
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.
What is the force that acts whenever two surfaces or objects mass put past one another-?
The force that acts whenever two surfaces or objects mass put past one another is friction
The two common forms of friction between two sliding surfaces presented in this course are?
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.
