how does moving a fulcrum on a lever change the amount of force needed to move an object
Because the force of gravity is no longer straight down on the object, it is at an angle. thus when you have a ramp some of the force due to gravity is dispersed in the x plane, causing the force down on the y plane (vertical) due to gravity ( mass x gravity) to be less thus decreasing the amount of force needed to lift.
Inertia is a measurement of the amount of energy needed either to start the object moving, or to slow down or stop its movement. This depends upon the mass (weight) of the object, but more particularly its change of speed. The greater the mass (weight) of the object the greater the amount of energy needed to move it and stop it.
The values of work found for different lengths of inclined plane depend on the mass of the object being moved and the angle of the incline. Generally, as the length of the inclined plane increases, the amount of work required to move the object decreases. This is because a longer incline allows for a smaller vertical distance over which the gravitational force acts, reducing the amount of work needed. However, the angle of the incline also plays a role, as a steeper incline requires more work to move the object regardless of its length.
The advantage to using an incline plane (ramp) is that it reduces the amount of work.

I don't know. Tell me for sake Fv= mg is the force needed to counter the force of gravity vertically. Fs = mg sin(a) is the force needed to counter the force of gravity up an incline.

( Assuming mass of object on incline plane is in kilograms (kg) ) . Force pulling down incline on object (kilogram force) = object mass * sin (incline angle) . Force of object acting on and normal to incline (kilogram force) = object mass * cos (incline angle) . Mechanical Advantage = 1 / ( sin ( incline angle ) )
Yes. It is easier to push an object up a plane than lift it straight up. It does not reduce the total amount of energy needed to lift it up.

Yes, it makes it easier to push the object up.

increases the distance an object travels, but reduces the force needed to raise the object to a higher level
