(Pg 107 has the list)

3. SCALAR VS VECTOR magnitude magnitude and direction Speed velocity
Distance displacement
acceleration
Mass weight
force

4. Resultant A vector that represents the sum of two or more vectors
Look at figure 4 on page 84
How can I get to the cafeteria from here?
The resultant is the same no matter what way you go.

5. Rules for Vectors
Vectors can be moved parallel to themselves in a diagram.
2. Vectors can be added in any order.
To subtract a vector add its opposite.
Multiplying or dividing vectors by scalars results in vectors

6. Remember Vectors in the same direction are added
Vectors in opposite direction are subtracted
Vectors at an angle use Pythagorean’s theorem and tangent of the angle
