1. Motion Year 10 Chapter 2.01-2.05

2. Do Now: Michael is caught in the hallway without his tie on by Mrs. Fox. He is able to run 18.7 m in 3.1 s before she catches him to give him a detention. What speed was Michael running to get away from Mrs. Fox?

3. Speed vs. Velocity

4. Example: A car travels 600 m in 30 s. What is the average speed? Why is the actual speed of the car usually different at a specific time?

5. Velocity Positive – Up and to the right Negative – down and to the left

6. Example: Nicky sees Mr. Porter at the end of the hall. He was trying to sneak food into the lab. Nicky casually walks backwards 15 m in 6.2 s to escape being caught. What is his velocity?

7. Acceleration

8. Example: A motorcycle travelling at 20 m/s, takes 5 s to stop. What is the acceleration?

9. Activity Find your acceleration!

10. Do Now: A truck traveling at 25 m/s puts its brakes on for 4 s. This causes a deceleration of 2 m/s 2. What is the truck’s new velocity? A car is traveling at a constant speed of 30 m/s for 30 s. What is the car’s acceleration?

11. Motion Graphs What is the speed of the moving object?

12. Gradient

13. What can you learn about the speed? Create a distance-time graph for the balloon

14. Describe the Motion

15. Speed vs. Time Graphs What is the acceleration? Distance travelled?

16. Describe the Motion Describe the motion Determine the distance travelled.

17. Create your own Based on the previous lab, create your own motion graphs. – Distance vs. Time – Speed vs. Time

18. Homework: Page 29 #1-2 Only 2 problems!

19. Do Now: Find the total distance traveled:

20. Create a graph of the acceleration:

21. Create a Velocity Graph:

22. Which of the graphs shows that one of runners started 10 yards further ahead of the other? Explain your answer.

23. In which of the following graphs below are both runners moving at the same speed? Explain your answer

26. Which runner won the race? Explain your answer.

27. Which runner stopped for a rest? Explain your answer

28. How long was the stop? Explain your answer.

29. How long did Bob take to complete the race? Explain your answer

30. Calculate Albert’s average speed.

31. Create a Velocity Graph

32. Motion Graphs Distance – Gradient = speed Speed (or velocity) – Gradient = acceleration – Area under the curve = total distance Acceleration
