I'm trying to teach myself Newton forces and am struggling with the end of chapter problems. Every problem seems totally different than the last but when I read the solution it's always some derivation of F=MA.
Is there a systematic approach or set of procedures that would help solve these problems?
Or alternatively, is there a way to categorize problems (boxes sliding, boxes sliding on inclines, boxes on pulleys, etc)?

It sounds like you're mainly doing problems where a force diagram would be helpful. Note that the F =mA can be described as net force. So what you can do is draw out all of the forces acting on the object and figure out what the net force is and therefore the acceleration etc. This can be tricky when you have things like inclines as the forces' direction becomes more difficult to figure out but a properly draw force diagram should see you through.

As the coach said to his athletes practice is the way to victory. :>)
The unfortunate truth is that such things don't make sense until they are practiced (done) over and over until the experience causes one's mind to comprehend.
The only shortcut I know to that of practice on UR own, is to also have a mentor/teacher who can reduce the time it takes only by demonstrating the methods and answering those questions specific to UR points of confusion.
