34. How is a vector represented?
( starting point ( direction B
A ) A )B Y
X ( line of action XY
)
(the length of AB line
segment
35. How is a vector represented?
( starting point ( direction B
A ) A )B Y
X ( line of action XY
)
(the length of AB line
segment
Vectors are usually bold typed and represented by an arrow
above the letter.
For instance: Force ( F )

For instance: Force ( F )
The magnitude of a vector is represented by the absolute value
of the vector and it doesn’t have the arrow above the letter.
F =F

Sin θ = Opp./Hyp.
Hypothenous
Opposite

Cos θ = Adj./Hyp.
Adjacent

60Âş
40. Addition and Subtraction
Vectors can’t be added and subtracted the same way scalar
quantities can. Different rules apply because vectors
involve direction.
There are 2 different methods for graphically adding or
subtracting vectors. Either one will produce the same results.
•Parallelogram
•Polygon Method
The new vector formed from the vectors added or subtracted
is called the resultant vector.
