No, I am not going to ask you what the difference between those two are. =P
I know the differences, but at the beginning of this term, my class started to learn about electricity and magnets, and that stuff.
Now, vector quantities are those that have direction and scalars are those without directions.
But then my teacher says... to put a +/- in front of an answer if it is a scalar quantity and to not put anything in front of an answer if it is a vector quantity.
What the heck? That really threw me off.
Could someone clarify on why we need to do that please? @_@
