1. Lesson One – Position, distance and Displacement

2. Position Position is the location of an object in space and time.
Position is measured from a fixed location in space called the “origin” or “zero”
Positions can be measured in One, Two or Three dimensions.
We will study motion in one dimension in this course.

3. Position-Time Graphs http://phet.colorado.edu/en/simulation/moving-man
What does a “flat line” mean?
What does the slope of the line tell us?

8. Distance = 40m

9. Distance
Distance is the amount of space an object passes through in a period of time.

10. Displacement
Displacement is an objects change in position over a period of time.

11. Displacement = 0
