Vectors
A vector is a quantity that has both magnitude size and direction
Eg Velocity excelleration force and momentum
Direction is important in all these
Vectors can be written in Several ways
Consider a vector going
A to B B
This Vector
might be reffered
to as AB the Start and end
pay
points with an arrow overthe top
A
0 It might be lower case letter
in bold like a or a letter
underlined like a
A vector drawn on a coordinate grid can also be
represented
by two numbers in brackets in a column
top number shows horizontal dist between start endpoints
vertical dist
These arecalled column vectors
You might them from
recognise
translation
A 3
if we add a vector to itself we
as
a as
I
get a vector that is twice as long
and parratell
a tazza
if a vector is a scalar multiple of another
vector then they're paralell
Scalar multiple means multiplied by a number
