How does the coefficient of friction depend upon the normal force between the surfaces in contact?
-- 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 a contact force between two boxes?
It is an external force that pushes on two boxes in contact on a horizontal surface. You can determine the acceleration of the boxes and the magnitude of the force between them.
Does the frictional force depend on the area of surface contact?
No. Frictional force is independant of surface area.
Investigate-how friction increases with increase of size of an object?
The force of friction on an object is equal to the coefficient of friction times the force perpendicular to the surface (normal force). When the mass of an object increases, the normal force increases, and the force of friction also increases. However, because the equation does not involve surface area, increasing surface area has no affect on the force of friction.
Why does building foundations have a large horizontal area of contact with the ground?
this is because when the area of contact between the ground and the building increases the pressure exerted by the building will be less for the same force.
What does the force of friction between two objects in contact depend on?
The types of materials involved, any third party (like sand or grease), the surface finish of the two objects where they contact, the temperature of the interfacing surfaces, and the normal force.
Why is the force on the steering greater when the tire is flat?
There is more surface area contact between the road and the flat tire translating into more friction between the two surfaces, which increases the amount of force required to change direction.

Explain differences between contact and noncontact?
A non-contact force is any force applied to an object by another body that is not in direct contact with itexample:A human body's weight is a non-contact force exerted by the Earth on their massa contact force is a force between two objects (or an object and a surface) that are in contact with each other.exampleAn example of contact force commonly encountered in college-level physics is the force between two masses A and B which are lying next to each other and a force F
What happens to friction if the force pushing surfaces together increases?
the larger the force pushing the two surfaces together the stronger the microwelds will be , because more of the surface bumps will come into contact , to move one surface over an other , a force must be applied to break the microwelds .

What is surface roughness tester?
surface roughness tester is the machine which used to measure the roughness of the surface using probes... roughness is nothing but the frictional force applied by the surface to the adjacent surface.. if roughness increases the amount of frictional force increases..
When do the frictional forces between two surfaces increase?
As they come into contact so tight friction would increase As roughness increases frictional force too increases.
