Force is porportional to area. A purely (theoretical) flat surface will have equal amounts of force applied to every point in contact, provided that the object weighs the same in each point.

On a flat surface the coefficient of friction is a ratio between and the weight of the object?
The force of friction!
What is the force that slows down an object rolling along on a perfectly flat surface?
friction
Does magnitude of normal force always equal the weight of the object?
No, not always directly opposite. The normal force is always perpendicular to the surface. So for a flat ground it will be directly opposite gravity or Weight.If you had an object on a ramp the normal force would be a diagonal line that is perpendicular with the ramp.
How can the force of friction be reduced?
Friction can be caused by many things, but generally it is the result of rough surfaces touching other rough surfaces. We calculate the force of friction on an object by multiplying the coefficient of friction for that object AND THE SURFACE IT'S TOUCHING (µ) by the force of gravity acting upon the object (if the object is on a flat surface--if not, you take the component of gravity perpendicular to the surface the object is resting on)--that is, the object's weight. In order to reduce µ efficiently, one could try to lubricate the object, or to sand down any wood surfaces, etc. to make both sides as smooth as possible.
How friction affects motion?
Friction is a very helpful thing and with out it you couldn't move, speed up, slow down, change direction, bend, or twist. Without friction nothing would ever happen. Friction can oppose motion or it can make it difficult for an object to move across a surface. Friction both helps an hinders every thing we do.the object would not move without frictionThe friction acts in the opposite direction to that of direction of motion.So friction slows the object and if no external force is applied the object will come to stop.Friction is a force that opposes the direction of motion between two materials. It is parallel to the surface your object is touching. Friction depends on the coefficient of friction and the normal force (force exerted perpendicular to the surface your object is on; opposes gravity on a flat surface). There are two kinds of friction: static and kinetic. Static friction must be overcome in order to move an object. Once the object is in motion the friction acting on it is called kinetic. Static friction has a threshold of force that is needed to get the object moving but once the object is in motion it can be moved at a constant velocity with less force required.

The force of friction!
What is the force that slows down an object rolling along on a perfectly flat surface?
friction
How does a flat shaped object float?
Well it depends on the density of the object and the density of the liquid that it is placed in. The object produces a buoyant force that lifts it to the surface of the liquid.
Does a bathroom scale read force?
yes a scale reads a force. called the normal force which on a flat surface equals your mass times gravity
Calculate surface area of round flat object?
A flat round object is a circle. Surface area of a circle = pi*radius squared.
Does magnitude of normal force always equal the weight of the object?
No, not always directly opposite. The normal force is always perpendicular to the surface. So for a flat ground it will be directly opposite gravity or Weight.If you had an object on a ramp the normal force would be a diagonal line that is perpendicular with the ramp.
How the friction is called somewhat evil in our life?
Because it takes all the F=μN out of our lives! F- Force in Newtons (N) μ - Greek letter Mu (Coefficient of friction with no units) N-Normal force (force perpendicular to surface measured in newtons N) (found using mass * gravity assuming you're on a flat surface) When a surface has a lot of friction, the force applied is lowered due to the higher friction coefficient. When there's more friction, it takes more force to move an object on a surface.
How do you find the surface of a 3D object?
on a 3D object to find the surface is to look on all flat surfaces. yourwelcome
If an object is placed on a flat surface the what is straight up and is equal to the weight of the object?
inertia
What object has at least one curved surface and one flat surface?
half circle
The outside area of an object that may be flat or curved?
Surface
Does a circle have a flat surface?
In geometry, a circle is a two-dimensional object, so it does not have a surface. Only three-dimensional objects have surfaces. A disc is a flat, circular three-dimensional object.
