Altitude of a rocket as compared to its mass and initial speed, in the absence of air resistance.

1. Altitude of a rocket as compared to its mass and initial speed, in the absence of air resistance.

2. Determine which rocket will go the highest. All rockets will be launched vertically from the ground.

3. Drawings and speed animations not drawn to an exact scale All numbers are given in generic units

4. All diagrams on the right will be compared to this same rocket on the left. Left Mass = 10 Speed = 10

5. Raise your left hand if you think the diagram on the left will go the highest Raise your right hand if you think the diagram on the right will go the highest

6. Ready • #1

7. Left Right #1 ANSWER Mass = 10 Speed = 10 Mass = 10 Speed = 20

8. Left Right #1 Correct! Mass = 10 Speed = 10 Mass = 10 Speed = 20

9. #2

10. Left Right #2 ANSWER Mass = 10 Speed = 10 Mass = 10 Speed = 1

11. Left Right #2 Correct! Mass = 10 Speed = 10 Mass = 10 Speed = 1

12. #3

13. Left Right #3 ANSWER Mass = 10 Speed = 10 Mass = 20 Speed = 10

14. Left Right #3 SAME Mass = 10 Speed = 10 Mass = 20 Speed = 10

15. #4

16. Left Right #4 ANSWER Mass = 10 Speed = 10 Mass = 100 Speed = 100

17. Left Right #4 Correct! Mass = 10 Speed = 10 Mass = 100 Speed = 100

18. #5

19. Left Right #5 ANSWER Mass = 10 Speed = 10 Mass = 1 Speed = 100

20. Left Right #5 Correct! Mass = 10 Speed = 10 Mass = 1 Speed = 100

21. #6

22. Left Right #6 ANSWER Mass = 10 Speed = 10 Mass = 5 Speed = 20

23. Left Right #6 Correct! Mass = 10 Speed = 10 Mass = 5 Speed = 20

24. #7

25. Left Right #7 ANSWER Mass = 10 Speed = 10 Mass = 100 Speed = 10

26. Left Right #7 SAME Mass = 10 Speed = 10 Mass = 100 Speed = 10

27. So, how can you determine which rocket will go higher by knowing its initial mass and speed, in the absence of air resistance?

28. A B C Put these three rockets in order from highest to lowest ANSWER A • Mass 10 • Speed 10 B Mass 10 Speed 20 C Mass 20 Speed 10 • * B highest A and C are tied

29. How would air resistance affect the altitude?
