1. Are you moving (Q&A)
Q: Have you ever been in a stopped car and thought yours was rolling because the car beside you moved?
A: Yes
Q: Why does it feel that way?
A: You were using the car as reference point to determine whether you were moving or not
Q: So how can you be SURE you are moving?
A: If your position changes from a stationary reference point!! Note the stationary part.

2. Distance vs. Displacement
And other motion-related topics

3. Motion
Every object has a position, a place in reference to other objects
Ex. You are seated to the right of billy and to the left of bob and in front of Jane and behind timmy
These objects that we use for reference are called reference points and they describe a relative position
If your relative position changes then we must say that motion has occurred!

4. Changes in Position
When position changes we know that motion has occurred and therefore a distance has been traveled
Note that DISTANCE is how far something actually traveled to get from one place to another, regardless of the path
DISPLACEMENT is how far two points are from one another in a straight-line
Let’s examine these differences in terms of how to get from Salisbury to Charlotte (see overhead)
