1. Position vs time graphs Of an object at rest

2. Describe what the object is doing at 1 second, 2 seconds, 3 seconds, etc.? position time 1 m 2 m 1 s 3 s2 s 4 s 5 s 3 m 4 m 5 m At 1 seconds the object is located 4 meters from the origin 0 s 0 m

3. Describe what the object is doing at 1 second, 2 seconds, 3 seconds etc.? position time 1 m 2 m 1 s 3 s2 s 4 s 5 s 3 m 4 m 5 m At 2 seconds the object is located 4 meters from the origin 0 s 0 m

4. Describe what the object is doing at 1 second, 2 seconds, 3 seconds etc.? position time 1 m 2 m 1 s 3 s2 s 4 s 5 s 3 m 4 m 5 m From 0 to 5 seconds the object is located 4 meters from the origin 0 s 0 m

5. If an object is staying in the same position for a time interval than its… at rest. stopped. not moving. still. Represented by a horizontal line on a position vs time graph

6. Number your whiteboards from 1 to 3 and answer the question about the graphs

7. 1) When and where is the object at rest? position time 2 m 4 m 1 s 3 s2 s 4 s 5 s 6 m 8 m 10m 0 s 0 m

8. 2) When and where is the object not moving? position time 1 m 2 m 2 s 6 s4 s 8 s 10 s 3 m 4 m 5 m 0 s 0 m

9. 3) When and where is the object still? position time -1 m 0m 5 s 15 s10 s 20 s 25 s +1 m +2 m +3 m 0 s -2 m

11. 1) When and where is the object at rest? position time 2 m 4 m 1 s 3 s2 s 4 s 5 s 6 m 8 m 10 m 0 s 0 m From 2 to 4 seconds the object is located 6 meters from the origin

12. 2) When and where is the object not moving? position time 1 m 2 m 2 s 6 s4 s 8 s 10 s 3 m 4 m 5 m 0 s 0 m From 0 to 4 seconds the object is not moving at 4 meters away From 8 to 10 seconds the object is not moving at 3 meters away

13. 3) When and where is the object still? position time -1 m 0m 5 s 15 s10 s 20 s 25 s +1 m +2 m +3 m 0 s -2 m From 15 to 25 seconds the object is located -1 meters from the origin

15. What would a position- vs- time graph look like of your desk as measured from the chalkboard -for the entire class period? How would your graph be similar, different from your classmates?
