Day 48: Vector Addition Diagrams (or The Only Thing IWBs Are Good For)


Students were asked to make their own treasure maps that had a displacement of zero. (Silly, right?)

What pattern do we see? (All the diagrams are “closed.”)

Does the order of the list of directions matter? In other words, could the same set of paces yield an open diagram? (This is where the IWB comes in handy, as seen in the movie.)

The point is to extrapolate from the treasure map exercise is to see if the pattern of “open” (net displacement) and “closed” (no net displacement) vector addition diagrams for displacements also applies to forces.
