1
00:00:00,000 --> 00:00:02,797
[That one actually kind of looked like mine before]

2
00:00:02,797 --> 00:00:05,264
What is the middle one

3
00:00:05,264 --> 00:00:09,718
representing? What is it a graph of?

4
00:00:09,718 --> 00:00:13,045
[His speed]

5
00:00:13,045 --> 00:00:16,859
[The numbers since she jumped] Okay. 

6
00:00:16,859 --> 00:00:19,515
Speed that she fell,

7
00:00:19,515 --> 00:00:21,859
according to the numbers that she's been jumping, yes. 

8
00:00:21,859 --> 00:00:24,437
So, You guys are so funny how you make

9
00:00:24,437 --> 00:00:26,217
up numbers. It cracks me up. 

10
00:00:26,217 --> 00:00:28,265
You don't need numbers. 

11
00:00:28,265 --> 00:00:31,859
[I'm the only one who does that, and then everyone else does it]

12
00:00:32,671 --> 00:00:35,046
So in these first few seconds, 

13
00:00:35,046 --> 00:00:37,796
we talked about this actually when we imagined

14
00:00:37,796 --> 00:00:39,125
the first graph, and the first graph. 

15
00:00:39,125 --> 00:00:40,780
In the first few seconds when she begins to fall,

16
00:00:40,780 --> 00:00:42,155
what is true about her speed?

17
00:00:42,155 --> 00:00:44,186
[It's going... speeding up.]

18
00:00:44,186 --> 00:00:46,469
It's increasing. 

19
00:00:46,469 --> 00:00:50,250
What's your speed graph doing in the first few seconds. 

20
00:00:50,250 --> 00:00:53,750
[We started there.]

21
00:00:53,750 --> 00:00:57,780
[We didn't start at zero.] [Well because you're going down.]

22
00:00:57,780 --> 00:01:01,219
Kay. [You're above the ground.] Right, right. But hang on. 

23
00:01:01,219 --> 00:01:02,883
Think about you're situation. 

24
00:01:02,883 --> 00:01:07,906
In this case, you are graphing

25
00:01:07,906 --> 00:01:13,546
distance above ground. 

26
00:01:13,546 --> 00:01:17,438
Yes? In this case you are graphing

27
00:01:17,438 --> 00:01:20,234
[Oh, speed] Speed. Okay?

28
00:01:20,234 --> 00:01:24,031
Big difference. In this case distance above the ground.

29
00:01:24,031 --> 00:01:26,313
Well, you started off way above the ground.

30
00:01:26,313 --> 00:01:30,593
And you jumped down towards the ground. 

31
00:01:30,593 --> 00:01:34,421
In this case, you're talking speed. 

32
00:01:34,421 --> 00:01:38,733
Before you even jump, is your speed way up here?

33
00:01:38,733 --> 00:01:41,328
[No.] A really high, fast speed?

34
00:01:41,328 --> 00:01:43,890
Before you even begin to jump? [No.] No. 

35
00:01:43,890 --> 00:01:46,265
But as you begin your jump what does your 

36
00:01:46,265 --> 00:01:48,807
speed do again? [Increase.] Increase.

37
00:01:48,807 --> 00:01:52,218
Untill eventually... [It bounces.] Okay. 

38
00:01:52,218 --> 00:01:54,811
You're re-thinking that whole situation, only now

39
00:01:54,811 --> 00:01:57,311
it is speed over time. 

40
00:01:57,311 --> 00:02:00,998
[Oh...] Kay? So re-think that again. 

41
00:02:00,998 --> 00:02:03,718
And then you can talk to Katie about it.

42
00:02:03,718 --> 00:02:07,608
[So speed increases...]

43
00:02:07,608 --> 00:02:09,516
Which one do you like better? Which one are you looking at?

44
00:02:09,516 --> 00:02:13,733
[This one] Kay. [It has like the slow down and the fall] Okay. 

45
00:02:13,733 --> 00:02:15,699
And then as the graph trails off

46
00:02:15,699 --> 00:02:18,419
What you've shown, is trailing off

47
00:02:18,419 --> 00:02:21,665
on an increasing. So as you jump ends, 

48
00:02:21,665 --> 00:02:23,733
you're speeding up? [No]

49
00:02:23,733 --> 00:02:26,342
Okay, so again. Just think about it. 

50
00:02:26,342 --> 00:02:29,623
You know? And think as little increments

51
00:02:29,623 --> 00:02:30,858
of time go by.

52
00:02:30,858 --> 00:02:32,811
How is you speed changing?
