Follow path is a constraint which creates an animation in which the Object follows a Curve. You of course have to constraint it to a curve of some kind.
The Constraint PanelEdit
When you added a curve you've to click the "Animate Path" button, otherwise nothing will happen.
The "Follow Curve" checkbox is there to make the objects Forward Axis, here "Y", point in the direction of movement. Of course here you'll find the Forward axis choices and Up choice, weird they still got different layouts, but don't bother. Finally, the "Influence" slider.
Where To Use ItEdit
It can be very handy when you animate a roller-coaster or something that has to follow something else perfectly.
