... First Law: Every body remains in a state of rest or uniform motion (constant velocity) unless it is acted upon by an external unbalanced force. This means that in the absence of a non-zero net force, the center of mass of a body either remains at rest, or moves at a constant speed in a straight line ...

Study Notes
... If we draw the free body diagrams at three different points (A,B, and C), we see that the free body diagrams are all different. This means that the force side of Newton 2nd Law for each dimension is also changing as we move from A to B to C. This change is due to the constrained motion of the partic ...
