DEC 7 tut 7-1 vectors

yay the maths version of physics, fun class. anyways basic from what i remember from my time in physics is there is two kinds of vectors:

vector: has direction
scalar:has no direction

basically ; if the qestion says u are going 130km/h and does say anything about goes east west etc the it is a scalar
if the qestion say u are going 130 km/h at a direction heading west then it is a vector

so the line is the magnitude or the total distance, what ever the question is asking. the line must have an arrow head put on it or you will lose marks
NORTH SOUTH EAST WEST, north always is on the top unless told other wise.
there is also another meathod finding direction called bearing and north is 0, east is 090 south is 180, and west is 270. bearing is like a compass but it uses numbers instead of using names.

yay more physis terms
Displacement: how far in what direction; km miles etc
Velocity:how fast in what direction; km/h miles/h
force;how much force in what direction; N or called newtons

scale must a very important thing, should always always be cm = whatever it is
