1. Vectors A vector quantity has magnitude and direction Vector examplesScalar examples Velocitymass Displacementlength Accelerationvolume Forcetemperature Momentumenergy

2. Specification of direction Magnitude = E S W N N of E E of N

3. Vectors can be moved around A A

4. Vector addition (Parallelogram Method) A B A+B Draw A and B from the same point Complete parallelogram Join diagonal

5. Vector addition (Tip-to-toe method) A B A+B A B A B Place toe of B on tip of A Join toe of A to tip of B

6. Reverse Vector A -A A+(-A)=0

7. Vector Subtraction A B A-B=A+(-B) -B A-B Form -B Get A+(-B) using tip to toe Another method Place B to start at same point as A Join tip of B to tip of A A-B
