3. Vectors
Vector: A quantity that has both a magnitude and a direction.
4 Notations for Writing a Vector
(1) An arrow (2) Bearings: Angle is always
• length indicates magnitude. measured clockwise from North.
• tip indicates direction. Angle is always written as a three
digit number.
(3) [direction] [angle] [direction] (4) [angle] [direction] of [direction]

4. 4 Notations for Writing a Vector
(1) An arrow (2) Bearings: Angle is always
• length indicates magnitude. measured clockwise from North.
• tip indicates direction. Angle is always written as a three
digit number.
1cm = 10km
3cm 60°
Note: All of the above examples indicate the same vector.

5. 4 Notations for Writing a Vector
(3) [direction] [angle] [direction] (2) [angle] [direction] of [direction]
1cm = 10km
3cm 60°
Note: All of the above examples indicate the same vector.

6. State the direction of each vector in five ways.

7. ABCD is a parallelogram with AD = DE. Each
segment in the diagram is a vector. Answer the
following questions.
(a) Name a vector (b) Name a vector that
that is equal to AD is the opposite of AB
(c) Name a vector that (d) Name a vector that is parallel
is collinear with BA to but not equal to EA or EB

8. State the magnitude and direction of each vector.
scale: 1 cm = 10 m

9. State the magnitude and direction of each
vector. (You can determine the answer using ruler and protractor.)
