1. Vectors: Position and Displacement

2. How do you get to the 7-11 from school?

3. All distances and directions are generally stated relative to the reference point, which is your starting point!

4. Your position is the separation and direction from a reference point.
For example:
you could be 2 blocks north of the reference point.

5. you could be 2 blocks north of the reference point.
For example:
you could be 2 blocks north of the reference point.
This is your displacement: the change in position

6. A vector quantity has both size (magnitude) (with units) and direction
A quantity that involves a direction, such as a position, is called a vector quantity!
A vector quantity has both size (magnitude) (with units) and direction
Example: 73 m [N]

9. Example: the mass of an object
A quantity that involves only size (magnitude), but not direction, is called a scalar quantity.
Example: the mass of an object

10. Speed vs. Velocity Speed = scalar Velocity = vector
*Note: the arrows above speed and distance show that they are VECTORS (direction and mag)

11. Working with Vectors Drawing/Representing Vectors
Vectors are represented by arrows, where the head of the arrow is pointing in the direction of the vector.
