Vector Addition
Questions:
1) Is vector addition commutative? Explain why or why not.
2) Explain, in you own words, how to add any 2 vectors geometrically.
3) Is it ever possible for the resultant (sum) of two vectors to be the zero vector?
If so, describe the relationship that must be true between these 2 vectors.
4) Can you devise a geometric method (like the one above) to subtract 2 vectors?
If so, how would you do this?
