## Presentation Transcript

1. Unit 1 Test Review

2. Write the mathematical expression for Object 1 Position = -2(m/sec)*time + 90(m) tIme (sec) Position (meters) 45 90

3. Predict the position at 100 seconds. Position = -2(m/sec)*time + 90m time (sec) Position (meters) 45 90 x = - 110 meters

4. What is the same at the point where the objects intersect. A B The position

5. Are the velocities constant? A B Yes, it is a straight line.

6. Draw a motion map for each object on the same line. A B

7. What is the velocity at 17 seconds? -8 m/sec time (sec) Position (meters) 45 40 30 20 15

8. What is the velocity at 40 seconds? 2.6 m/sec time (sec) Position (meters) 45 40 30 20 15

9. What is the total distance travelled? 80 m time (sec) Position (meters) 45 40 30 20 15

10. What is the total displacement? 0 m time (sec) Position (meters) 45 40 30 20 15

11. Make a motion map. time (sec) Position (meters) 45 40 30 20 15

12. Look at the motion map below and make a position vs time graph x t
