Of the two forms of friction you studied friction is generally the hardest to overcome?
Static or Kinetic
In a machine what force does the effort force try to overcome?
It depends, there are two forces, the load's inertia and friction.
What are the sources of friction?
Friction occurs because of the interactions between two surfaces that are in contact. When either of the surfaces experiences motion, its friction that resists the same. Wheels moving on a surface will produce friction.
What are two sources of friction?
Not sure if you mean 2 types of friction. Two types of friction can be just friction with the ground, and air friction such as drag on any vehicle, or any type of flying machine. Other objects can have air friction too, but not as much as something moving at a higher rate of speed.
Two times when friction is useful?
1. when walking so you do not slip everywhere 2. driving (same reason)

Of the two forms of friction you studied friction is the one that must be overcome in order to start something moving?
static
Is rolling friction greater than sliding friction?
Typically not. However rolling friction is somewhat of a myth. Rolling friction is actually caused by static friction. There are really only two types of friction: Static and Kinetic. That's it! Rolling friction is caused by static friction and the coefficient of friction (which determines its strength) is dependent upon the two materials of interaction.
Why is gravitation and acceleration the same?
They are not. Gravitation is a force and forces (if they can overcome friction) will cause accceleration. The two are not the same.

What is friction what causes it and wahat does it do?
Friction is a force that acts on all touching objects. Friction is caused by the roughness of on object. Even if an object feels smooth to the touch, it will never be perfectly smooth because there will always be microscopically small peaks and valleys at the atomic level. What friction does is essentially try to prevent an object from moving or continue moving. There are two types of friction, static and kinetic. Static friction must be overcome to get something moving, kinetic friction must be overcome to keep something moving. They both have values that depend on the two surfaces touching and are referred to as the coefficient of their respective term. Note: the coefficient of static friction is always higher than that of kinetic for the same two materials.
What is static friction in sliding friction?
the static friction in sliding friction is different......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................lol
Forces of any two materials the force required to overcome sliding fiction is greater than the force to overcome starting friction?
If I understand the question correctly: It is actually ill-posed. The frictions you are refering to are dynamic (sliding) and static (starting). I think you will find that static friction is always harder to over come than dynamic friction, not vice-versa.
Of the two forms of friction which is generally the hardest to overcome?
Friction depends on the roughness of the surface between the objects, it also depends on the area in contact between the objects. Athletes can have spikes on their shoes to maximise friction with the ground.
