Nope. It's to help the centripetal force so you won't swirl out. It's in the physics of the thing. . . . Don't quite completely understand it myself.

What happened to the coefficients of friction as the surface area of the contact increased?
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 juice temperature increase with increasing convective heat transfer coefficient at any constant kettle surface temperature?
Yes, the juice temperature increases with an increasing convective heat transfer coefficient at any constant kettle surface temperature. The convective heat transfer coefficient represents the efficiency of heat transfer from the kettle to the juice. As the convective heat transfer coefficient rises, more heat is transferred from the kettle surface to the juice per unit of time. This increased efficiency results in a faster temperature rise in the juice. Therefore, a higher convective heat transfer coefficient enhances the overall heating process, leading to a greater temperature increase in the juice even when the kettle surface temperature remains constant.
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 the function of coefficient of static friction?
This coefficient of static friction is needed to find the frictional force between a body and a surface on which body has to move. If u (mu) is the coefficient of friction then uR gives the frictional force between moving body and surface. There is no unit for coefficient of friction. Here R is reaction which equals to the weight of the body
On a flat surface the coefficient of friction is a ratio between and the weight of the object?
The force of friction!

What does the slope of the static friction vs normal force represent?
the slope of static friction & normal force represents "coefficient of friction' which is constant for a particular surface
On a flat surface the coefficient of friction is a ratio between and the weight of the object?
The force of friction!
Does the surface area of an object affect the amount of friction between the object and the surface?
No, it doesn't, the only important thing is the force perpendicular to the surface (weight) and friction coefficient.
What factors does the time constant of a thermocouple depend on?
It depends on the mass (m), specific heat (c), convective heat transfer coefficient (h) and the surface area (As) In other words, Time Constant = (m * c) / ( h * As)
What factors determine the coefficient of friction?
quality of the Surface is affected to the Coefficient of friction
How do you decrease friction between two surface?
1. Decrease the Force between the two Surfaces. 2. Lubricate the Surfaces, thus lowering the Coefficient of Friction between them.
