1. My Bland and Maybe Boring Motion PowerPoint

2. What is

3. Did you remember?

4. What does this represent?

5. The change of position by an object or a particle during the interval [some people say the amount of displacement]

6. What is

8. What is

9. Is the total distance traveled by the particle during the time interval t=0 to t=13

10. If given the velocity graph, then how do you know when the particle or object changes direction?

11. The particle, object, or living creature will change directions if the graph of the velocity changes from positive to negative values or negative to positive values.
You must be explicit [specific] in your explanation!

12. How do you know if the speed of a particle [or object or living creature] is decreasing?

13. SPEED DECREASING The speed will be decreasing at some time t if:
a(t)<0 while v(t)>0 OR
a(t)>0 while v(t)<0.
Please remember that you must explicitly describe what is happening at some specific time t.

14. How do you know if speed is increasing at some specific time t?

15. SPEED INCREASING Speed is increasing at some specific t if:
a(t)>0 while v(t)>0 OR
a(t)<0 while v(t)<0
Once again, you must be explicit about what is happening at some specific time t.

16. If given position, say, s(1) and the velocity function, v(t), then how could you find s(8)?

17. How to find s(8)
Remember: Initial position PLUS accumulated rate of change
