### Acceleration in 1D Review

2. 2. There are three types of graphs:• Position vs. Time – Shows the position of an object over time• Velocity vs. Time • Shows the rate at which the position of an object changes over time• Acceleration vs. Time – Shows the rate at which the velocity of an object changes over time
3. 3. Position vs. Time
4. 4. Velocity vs. TimeQUANTITATIVE (with numbers)QUALITATIVE (without numbers)
5. 5. Different Velocity-Time Graphs (all show changing velocity)
6. 6. Do the Dance!!!= sign (+/-) of velocity sign (+/-) of acceleration =
7. 7. Complete with motion mapsDIFFERENT SITUATION EXAMPLESOF MOTION
8. 8. Acceleration vs. TimeConstant Velocity (a=0) Constant Acceleration (a≠0)
9. 9. Now, test yourselfLook at the following position time graphs, andsee if you can describe the motion of the object represented by the graph in complete statements
10. 10. Answer• Constant velocity• Moving in the positive direction• Away from the origin
11. 11. Answer• Slowing down in the negative direction• Toward the origin• Stopped for an instant• Turns around• Speeding up in the positive direction• Away from the origin
12. 12. Answer• Slowing down in the positive direction• Stops for an instant• Speeding up in the negative direction
13. 13. Answer• Slowing down in the positive direction• Away from the origin• Then comes to a stop
14. 14. Answer• Speeds up in the positive direction• Away from the origin
15. 15. Answer• Slowing down in the negative direction• Toward the origin• Then comes to a stop
16. 16. Answer• Stopped -OR-• Not moving
17. 17. Answer• Does not start at the origin• Constant velocity in the positive direction• Away from the origin• Stops for some time• Turns around• Constant velocity in the negative direction• Toward the origin
18. 18. CHALLENGE QUESTION
19. 19. (CHALLENGE) Answer• Slows down in the positive direction• Stops for an instant• Speeds up in the negative direction• Constant velocity in the negative direction• Slows down in the negative direction• Stops for an instant• Speeds up in the positive direction
20. 20. How’d You Do?• If you did well, then you’re set!• If you need more practice, check the other notes/resources on the website and review this presentation
