-- The friction force changes, and is directly proportional to the normal force.

-- The coefficient of friction doesn't change. It is the proportionality constant

in the first statement.

What is the maximum static friction that can be exerted between two surfaces in contact?

The maximum static friction that can be exerted between two surfaces in contact is equal to the coefficient of static friction multiplied by the normal force between the surfaces.


The the value of the coefficient of friction the greater the resistance to sliding.?

What is coefficient of friction..?

A higher coefficient of friction indicates that two surfaces in contact have a greater resistence. A lower coefficient of friction indicates that the two surfaces in contact have less resistence. Soccer cleats on grass have a greater coefficient of friction than skates on ice.

Is the coefficient of friction independent of the narmal force?

No, the coefficient of friction is not independent of the normal force. In fact, the coefficient of friction is defined as the ratio of the frictional force to the normal force between two surfaces in contact. It is a material property that quantifies the resistance to sliding between the surfaces.


What is the coefficient of friction for talcum powder.?

The coefficient of friction for talcum powder can vary depending on the surfaces it is in contact with. On average, talcum powder has a low coefficient of friction due to its fine, powdery texture. It is commonly used to reduce friction between surfaces.


What is the maximum static friction force that can be exerted between two surfaces in contact?

The maximum static friction force that can be exerted between two surfaces in contact is equal to the product of the coefficient of static friction and the normal force pressing the surfaces together.


What are the two factors that affect the friction force between two surfaces?

The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.


What factors determine the coefficient of friction?

The coefficient of friction is determined by the nature of the materials in contact, surface roughness, pressure between the surfaces, and the presence of any lubricants or contaminants. It is a dimensionless quantity that represents the ratio of the force of friction between two surfaces to the normal force pressing the two surfaces together.


How the coefficient of friction between a body and a surface change if the mass of the body is doubled?

The coefficient of friction between a body and a surface does not change if the mass of the body is doubled. The coefficient of friction is a property of the material of the surfaces in contact and their interaction, not the mass of the body.


Is the coefficient of friction constant in this scenario?

In this scenario, the coefficient of friction is constant if the surfaces in contact and the conditions remain the same.


What factors influence the coefficient of friction?

The coefficient of friction is influenced by factors such as the roughness of the surfaces in contact, the materials of the surfaces, and the presence of any lubricants or contaminants.
