What else can I help you with?
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.
Third class levers have the force between the fulcrum and the resistance?
Yes.
The coefficient of friction is a blank number that represents the resistance to sliding between two blank in contact with one another?
Unitless, surfaces
The of friction is a number that represents the resistance to sliding between two surfaces in contact with one another?
The coefficient of friction is a dimensionless value that quantifies the amount of friction between two surfaces. It is dependent on factors like the materials of the surfaces and the force pressing them together, and it helps predict the amount of force required to overcome friction and initiate sliding.
The of friction is a number that represent the resistance to sliding between two surfaces id correct with one another?
coefficiant
What is the blank the value of the the coefficient of friction the greater the resistance to sliding?
The coefficient of friction represents the resistance to sliding between two surfaces. A higher coefficient of friction indicates greater resistance to sliding, while a lower coefficient of friction indicates less resistance.
How does the roughness of surfaces that are touching affect the friction betwen the surfaces?
Rough surfaces will have more contact points, creating more friction due to the increased resistance between the surfaces. Smoother surfaces have less contact points, resulting in lower friction because there is less resistance between the surfaces.
What is the resistance to movement on surfaces that touch?
The resistance to movement on surfaces that touch is called friction. It is caused by the interaction between the irregularities of the two surfaces, which creates a force that opposes the motion of the objects.
What is the force between two moving surfaces in contact called?
The force between two moving surfaces in contact is called friction. Friction is caused by the resistance encountered when one surface slides or attempts to slide over another.
The the value of the coefficient of friction the greater the resistance to sliding.?
higher
What value of the coefficient of friction the greater the resistance to sliding?
The greater the coefficient of friction between two surfaces, the greater the resistance to sliding between them. The coefficient of friction is a measure of the amount of friction between two surfaces, with higher values indicating a stronger resistance to sliding.
Why do polishing and lubricating decrease friction?
Polishing smoothens the surface roughness, reducing the contact points between surfaces and lowering friction. Lubricating creates a barrier between surfaces, allowing them to slide over each other with less resistance. Both processes help reduce friction by minimizing the resistance encountered when surfaces come in contact and move relative to one another.
Why does friction occur on an objects surface?
Friction occurs on an object's surface due to the interaction between the roughness of the surfaces in contact. As the surfaces move against each other, the irregularities in the surfaces interlock and create resistance to motion. This resistance results in the force of friction, which opposes the relative motion between the surfaces.
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
