What happened to the coefficients of friction as the surface area of the contact increased?
Wiki User

As the coefficient of friction is not function of the area or not related to the area of the contact surface so the coefficient of friction remains constant on the increase of the contact area. The coefficient of friction depends upon the material of the friction surfaces only.

Does the nature in contact influence friction force?
Since friction means a contact force, the nature of contact will influence friction force. Smoothness of objects affect the friction force. However, as contact pressure rises, the friction does not rise.
Does friction depend on the area in contact?
The force of friction does, but the coefficient of friction does not.
How is rolling friction caused?
How is rolling friction caused
What is the relationship between contact force and friction?
Generally, the higher the contact force, the higher the friction.
Is friction contact or non-contact force?
non contact
What happened to the coefficients of friction as the surface area of the contact increases?
As the coefficient of friction is not function of the area or not related to the area of the contact surface so the coefficient of friction remains constant on the increase of the contact area. The coefficient of friction depends upon the material of the friction surfaces only.
How friction increased?
With increased surface areas in contact, friction increases.
When the block of mass is increased is there an increase in the value of coefficient of kinetic friction?
No, coefficient of friction is dependent on the materials in contact, not their mass. However the FORCE of friction will increase as the mass increases in this case.
Does the nature in contact influence friction force?
Since friction means a contact force, the nature of contact will influence friction force. Smoothness of objects affect the friction force. However, as contact pressure rises, the friction does not rise.
Why is the co efficient of kinetic friction less than static friction?
Because it's harder to get something to start moving than keep it moving if it already is. Coefficients of friction are merely constants dependent on the two surfaces in contact. Carpet has a higher coefficient of friction than ice because carpet has more microscopic bumps which oppose motion than smooth ice does.
Is friction contact or non contact?
Contact.
A horizontal force of 40 newtons will just start a 600 newton empty sled moving across packed snow what is the coefficients of static and kinetic friction?
static friction= normal contact force*coefficient of static friction 40 = (600*9.8) * CSF CSF=40/(600*9.8) (you can calculate that yourself, i cant be bothered) there isn't enough info to work out the coefficient of kinetic friction
Does friction depend on the area in contact?
The force of friction does, but the coefficient of friction does not.

Does fluid friction vary with speed and area contact?
Fluid friction will vary with speed and the area of contact when referring to air friction or drag. When referring to surface friction then only the area of contact will vary.
What is the relationship between contact force and friction?
Generally, the higher the contact force, the higher the friction.
Is friction contact or non-contact force?
non contact
