More Force Stuff

Last class, we cleared up more facts about forces and made this list:

We all agreed that on a force diagram if the forces are equal, they should appear equal and have congruency markings.  Those forces with unequal magnitude should appear unequal in length and not have congruency markings.  We also decided that the force diagrams will only show forces acting upon an object at one specific time, even if the object is already in motion caused by a different force.  Another thing the class decided was that all the arrows should come from the "dot" or object that the forces are acting upon.  As for initial velocity for an object that was already in motion, I think we should still include a side note of it because it is useful information for if we were doing a lab and made force diagrams for different situations.  I understand overall how to draw a basic motion map now.
