2.  A quantity that doesn’t involve direction is a scalar quantity. These include such things as distance, time and speed  A quantity that does involve direction is a vector quantity. These include such things as position, displacement, velocity and acceleration

3.  Displacement is the distance an direction traveled between the beginning and end of a trip. If we represent displacement on a number line then, 0 is the reference point. The positive numbers are one direction, usually forward or north or east and the negative numbers are the opposite direction, backward or south or west.

4.  If my lab is the reference point in the school, identify the displacement for the following places: ◦ The gym ◦ The IA shop ◦ The elementary school

5.  Another way to show vector quantities is to draw a line segment showing direction and size. This is called a vector. A vector must include size, units and a direction in a square bracket; for example 57m [N]. A vector quantity is represented by a symbol that has a small arrow over it,

6.  Choose a reference point  Decide on an appropriate scale and write it down. For example, 1cm=10km  Draw a line to the stated scale, and write the size of the vecotr next to the line  State the direction – usually N,E,W or S as a reference  Add an arrow pointing in the direction of the vector

7.  Using the correct displacement symbols and references identify the location of 3 different items in the classroom based on ________’s desk as a reference point.
