by increasing distance over which the force is applied
by increasing effort distance hence reducing the effort needed to work
when machines are used
By exchanging for for distance. You need to apply less force, but you need to apply it over a larger distance. Since work (or energy transfer) is force x distance, the total work is the same.
A machine decreases the amount of force needed to work, as it distributes the force throughout a larger distance.
the less force is needed.

Not usually. They can convert effort into distance and things like that, but the overall energy is about the same.
