Anytime forces are are unbalanced what is the result?

Any unbalanced force will produce an acceleration due to which the body will move

-- An unbalanced group of forces produces a 'net' force that's not zero. 

-- When the net force on an object is not zero, the object's motion is accelerated.  That means that either its speed or direction (or both) changes. 

It may speed up, slow down, or stay at the same speed but turn from a straight direction ... all of those are called 'acceleration'.
