What does the coefficient of static friction represent?
In free space or on a frictionless surface, it takes no force to move something. Where there is friction, the ratio of (force necessary to start it moving horizontally)/(the object's weight) is the coefficient of static friction on the horizontal surface.
How surface influences the amount of friction there is?
The larger the contact surface, the more friction. The more uneven the surface, the more friction. The material of the surface has also an effect on friction.
How does surface area affect friction?
more rough surface more friction object have
Which surface gives the least friction?
Plane surface with negligible friction.
What type of surface provides a lot of friction?
Rough surface provides lot of friction.
Horizontal force exerted on one surface by another when the surface are not in relative motion?
the static friction force curse McGinity

What is the amount of horizontal force required to start in motion an object sitting on a horizontal surface must be great than what?
multiply coefficient of static friction by object mass
What is cone friction?
A cone in which the resultant force exerted by one flat horizontal surface on another must be located when both surfaces are at rest, as determined by the coefficient of static friction.
Does the slant of an uneven surface create friction between the object and the surface?
What happens is gravity is pulling an object down, and if the surface it's resting on is slanted or uneven, there is a horizontal component to the force. That horizontal component attempts to move the object, however what CREATES the friction is the coefficient of kinetic friction (if the object is moving) or coefficient of static friction (if the object doesn't actually move) of the two surfaces. The two surfaces being the surface of the object that's touching the slanted surface and the slanted surface itself. These coefficients are determined by what the two surfaces are made of. Long story short, what CREATES the friction is the two materials touching each other. The slant just provides the force that attempts to move the object thus resulting in a visual representation of "friction."
The speed of ball increases as it rolls down an inclinem What happens to its speed on a smooth horizontal surface?
It's speed will reduce to to friction by gravity.
Why cyclists bend inside on circular track?
In short, you lean inside to reduce horizontal acceleration so that your weight is contributing as much as possible to the normal force (perpendicular to the surface of the track). Since friction force is coefficient of friction * normal force, if you are perpendicular to the surface you maximize friction and therefore the amount of grip you have. And because you are turning inwards, you are being "pulled" outwards, which balances the horizontal force caused by leaning inwards.
How surface influences the amount of friction there is?
The larger the contact surface, the more friction. The more uneven the surface, the more friction. The material of the surface has also an effect on friction.
What is surface friction is?
Surface friction ALWAYS point parallel to the surface and opposite motion. There must be a normal force for there to be friction
How does surface area affect friction?
more rough surface more friction object have
Which surface gives the least friction?
Plane surface with negligible friction.
How do surface affect friction?
