by increasing distance over which the force is applied
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.
Moving up an incline requires extra energy to counter the force of gravity.
A force machine does not reduce the amount of work that has to be done
When used appropriately, a pulley can be used to reduce the amount of force needed to move an object. By using multiple pulleys, one can change the direction that force needs to be applied to move an object, as well as reducing the amount of force that is necessary through mechanical advantage.

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.
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.

Reduce the friction
An inclined plane makes work easier because it allows for a longer distance over which a force can be applied. By exerting a smaller force over a longer distance, the amount of work required is reduced. However, the force exerted remains the same, as the incline does not change the magnitude of the force needed.

( 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 ) )

the amount needed is the amount that's taken by the bear
