The coefficient of friction is a blank number that represents the resistance to sliding between two blank in contact with one another?
Unitless, surfaces
What opposes motion between surfaces that are touching?
Force of friction
What is the source of friction?
Friction is a result of the interactions between surfaces that are in contact, more precisely, it arises from microscopic interactions between jagged natures of surfaces. Friction is present even when an item is not moving.
What are facts about air resistance?
What type of friction is air resistance?fluid friction. Air resistance is fluid friction. Air resistance occurs between the surface of a falling object and the air that surrounds it. Rolling friction occurs when a rounded surface moves over a solid and sliding friction occurs when a solid moves over another solid. Static friction occurs when a solid touches another solid but there is no movement.What two factors affect air resistance?size and shape. Size and shape are the two factors that affect air resistance. Air resistance works with surface area, so the more surface area, the more air resistance. Think about when you drop two pieces of paper: one crumpled and one flat. The crumpled one falls faster because there is less air resistance acting on the paper.
Why lubricant is used when metal parts rub together?
These substances are caused to insinuate themselves between the surfaces, and have the property of so separating them as to prevent serious abrasion. The solid and semi-solid lubricants seem to act as rollers between the surfaces, or form a film between them which itself suffers abrasion or friction. The liquid lubricants, however, maintain themselves as liquid films between the surfaces, upon which the bearing floats

The of friction is a number that represent the resistance to sliding between two surfaces id correct with one another?
coefficiant
Is the amount of friction greater between rough surfaces smooth?
smooth surfaces have less friction, take an ice rink for example, the resistance on that is less than the resistance on asphalt
Is the amount of friction greater between rough surfaces or or smooth surfaces?
rough surfaces because it has more bumps that stop it from moving faster
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.
What is the name of the force that will stop slipping?
Friction. It creates resistance between two surfaces and stops slipping.
Will friction resist in motion with rough surfaces?
Yes, friction is the force of resistance against motion between two surfaces. The rougher a surface is the higher its friction coefficient.
Will the speed of the object affect the amount of friction between object and the surface?
No. The speed of the object does not affect the amount of friction between an object and the surface. Friction is affected by the types of surfaces in contact, smoother surfaces produce less friction, and the weight of the object moving horizontally affects the resistance relative to the two surfaces in contact. Greater weight causes greater resistance.
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.
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.
What is the force acting between any two surfaces moving past one another?
Friction.
