1. Vectors

2. Vectors vs. Scalars ► Quantities can be divided into two categories - vectors and scalars. vectors and scalarsvectors and scalars ► A vector quantity is a quantity which is fully described by both magnitude and direction. ► A scalar quantity is a quantity which is fully described by its magnitude.

3. Examples of vector quantities include: ► displacement displacement ► velocity velocity ► acceleration acceleration ► and force. force

4. the quantity demands both a magnitude and a direction ► For example, suppose that your teacher tells you that "a bag of gold is located outside the classroom; to find it, displace yourself 20 meters."

5. Arrows ► Vector diagrams depict a vector by use of an arrow drawn to scale in a specific direction.

6. Positive & Negative ► Vectors going right (east) or up (north) are positive ► Vectors going left (west) or down (south) are negative

7. Vector Addition ► Two vectors can be added together
