What type of contact force is perpendicular to the surface of contact?
Normal force is the component perpendicular to the surface in mechanics. It prevents an object from penetrating the surface with the contact force exerted.
What can affect the amount of friction on an object?
the weight of the object, what its outside consists of, the nature of the surface it resting on.
Is it true that weight affects the amount of friction between the object and a surface?
Yes. Weight, being a force perpendicular to the surface, affects the magnitude of the friction, but not the friction coefficient.
If an aircraft is flying horizontally then its weight must be balanced by what force?
Lift balances weight. Thrust balances drag.
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.

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.
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.
If an aircraft is flying horizontally then its weight must be balanced by what force?
Lift balances weight. Thrust balances drag.
What is the root word sitting?
The root word in "sitting" is "sit." It is a verb that indicates the action of resting on a surface with one's weight supported by the buttocks and thighs.
What does balances measures?
it measures weight
what is the weight of a train?
It is the weight of the train and locomotive resting on the driving axles.
What is the dead weight of a train?
It is the weight of the train and locomotive resting on the driving axles.
What Tools are used for measururing weight?
Balances and scales.
What is function of bow in ship?
it balances the weight of the ship out
