1
00:00:20,484 --> 00:00:21,155
So what do you guys think. 

2
00:00:21,155 --> 00:00:24,468
For change in distance verses change in time. 

3
00:00:24,468 --> 00:00:26,234
Remember change in time is fixed. 

4
00:00:26,234 --> 00:00:28,670
But change in distance on this

5
00:00:32,036 --> 00:00:33,469
portion of his jump.

6
00:00:37,405 --> 00:00:40,091
How would you describe it? I mean it doesn't have to be in perfect

7
00:00:40,091 --> 00:00:43,186
mathematical terms. Just how would you describe it?

8
00:00:49,468 --> 00:00:50,054
Greg? What do you think?

9
00:00:56,204 --> 00:00:58,984
Pull from just this portion of his trip. After -

10
00:00:58,984 --> 00:01:01,780
[Part of it decreased and them from the bridge,]

11
00:01:01,780 --> 00:01:04,671
[His distance from the bridge.]

12
00:01:04,671 --> 00:01:06,248
Distance from the bridge is decreasing. 

13
00:01:06,248 --> 00:01:08,905
Okay? And so distance above the ground

14
00:01:08,905 --> 00:01:10,421
[it increasing]

15
00:01:10,421 --> 00:01:11,655
Is increasing, good. 

16
00:01:11,655 --> 00:01:14,186
Um, How do you think it's increasing. 

17
00:01:14,186 --> 00:01:16,926
Do you think it's increasing more each time? 

18
00:01:16,926 --> 00:01:18,576
Or is it increasing less each time?

19
00:01:18,576 --> 00:01:21,561
[It increasing more]

20
00:01:21,561 --> 00:01:23,388
It's increasing more each time. Class?

21
00:01:23,388 --> 00:01:24,498
[Yeah.]

22
00:01:24,498 --> 00:01:27,670
Yeah? Okay. So what's...

23
00:01:31,180 --> 00:01:33,992
Fast forward, fast forward...

24
00:01:33,992 --> 00:01:36,123
[He's about to hit his head.]

25
00:01:36,123 --> 00:01:37,811
Yeah, he's about to hit his head. 

26
00:01:37,811 --> 00:01:40,123
Okay, good. [Look how close he is.]

27
00:01:40,123 --> 00:01:41,920
Okay, can you guys see him?

28
00:01:41,920 --> 00:01:43,263
Barely?

29
00:01:43,263 --> 00:01:45,108
Did you already hear?

30
00:01:45,108 --> 00:01:47,980
I think he's about to fall again.

31
00:01:47,980 --> 00:01:49,030
Looks like it anyways

32
00:01:49,030 --> 00:01:50,171
I mean I don't know

33
00:01:50,171 --> 00:01:51,358
Because I don't know how many more frames I have.

34
00:01:51,358 --> 00:01:52,343
But I think he is about

35
00:01:52,343 --> 00:01:53,451
to fall again.

36
00:01:53,968 --> 00:01:55,828
What about his change in distance at this point?

37
00:01:56,750 --> 00:01:57,890
I'm going back and forth.

38
00:01:57,890 --> 00:01:59,000
[It's slowing?]

39
00:01:59,000 --> 00:01:59,983
Between one frame. 

40
00:02:01,953 --> 00:02:03,629
Compare to where I asked Greg, 

41
00:02:03,629 --> 00:02:04,611
is this change in distance

42
00:02:04,611 --> 00:02:05,766
less or more?

43
00:02:05,766 --> 00:02:06,531
[Less]

44
00:02:06,531 --> 00:02:09,031
Less, but is his distance still growing 

45
00:02:09,031 --> 00:02:10,171
in comparison to the ground?

46
00:02:10,171 --> 00:02:11,843
[yes] Yes, but...

47
00:02:11,843 --> 00:02:12,937
Okay, good. 

48
00:02:12,937 --> 00:02:15,418
Let's see, is he really about to fall?  Is that right?
