It has an effect a bit like a spring or rubber band - the interpolation will move much more quickly at one end than the other if you set the tension to one side of the other. If tension is balanced it effectively has no effect, and you'll get a straight interpolation. You could of course use the curves to get similar effects.. infact I've never used tension tbh :)
