Lab #2 - Problems Difference between displacement, distance and position Time, starts at 0.0s Slope (negative and positive) Best-fit line Labeling x and y axes Title Pencil! (not pen)

Review What is… Motion? The difference between vector and scalar? The difference between position and displacement? Distance? A reference point? Example?

Review Describe the following graphs 1. 2. 3.

5.2 Vocabulary Speed Constant Speed Changing Speed Average Speed Instantaneous Speed

5.2 What is speed? Speed – v The distance an object moves in a certain length of time Can you think of examples? What is the difference between constant speed and changing speed? Can you think of examples?

5.2 Do you remember the position-time graphs? Now, we look at “distance-time” graphs What is the difference between them? What can you see in a distance-time graph?
