D2

2-1 Define position.

2-2 Define displacement.

2-3 Define distance.

2-4 Define average speed.

2-5 Define average velocity.

2-6 Define instantaneous speed.

2-7 Define instantaneous velocity

1. Discuss how to get distance travelled from change in position (straight line motion)

2. Develop the idea of a displacement & displacement vector too? (1 Dimension) (use a number line)

3. Next discuss the idea of displacement vector in two dimensions. (Use a rectangle.)

4. Next discuss distance & displacement, speed and velocity.

Look at moving cart in logger Pro. 

5. Go over workbook Chapter 2: Linear Motion

6. Do Problems from text:
Q6, like 3 & 4, 9
