e.e..e the real definition of a vector is:"A vector is an oriented line segment"
then it mean that a vector is represented by: a direction and a power (lenght of the line segment)
then....if a thing..is affected by a vector...it will move..
ex:a boat on water... and wind (vector)
ok .. a wind (10km/h) at 45 degree
and the boat at 0,0 with NO FRICTION =)
then .. convert the vector in ...coordinate.. it do:
(7km on X)/h
(7km on y)/h
then...after ..you do what you want..
ex: after 10 minutes ..where will be the boat..
X=7km/h * 1h/60m * 10=1m
y=7km/h * 1h/60m * 10=1m
then ..your boat will be at (1,1) ..after 10 minutes....
ive learn so much in that "physique 054 534" course
