1
00:00:00,000 --> 00:00:02,781
No, as we talk about these things

2
00:00:03,702 --> 00:00:04,530
there's rules. 

3
00:00:05,375 --> 00:00:07,687
Kay? And the rules are on the board. 

4
00:00:08,313 --> 00:00:09,843
So that you don't forget them. 

5
00:00:09,843 --> 00:00:11,672
And if you break a rule, I will simply

6
00:00:11,672 --> 00:00:12,906
re-direct your attention to 

7
00:00:12,906 --> 00:00:14,438
the rule that you broke. 

8
00:00:14,438 --> 00:00:15,359
Kay?

9
00:00:15,359 --> 00:00:18,109
Um, When we talk about either

10
00:00:18,109 --> 00:00:20,079
the video or the graphs

11
00:00:20,859 --> 00:00:22,282
-doesn't matter which one

12
00:00:22,282 --> 00:00:24,734
When you speak about this situation in general

13
00:00:24,734 --> 00:00:27,157
you must speak about how distance

14
00:00:27,157 --> 00:00:30,774
changes as time changes. 

15
00:00:30,774 --> 00:00:33,002
Don't tell me what Samone is doing. 

16
00:00:33,002 --> 00:00:34,548
Don't tell me Samone bounced.

17
00:00:35,859 --> 00:00:40,469
Tell me how distance changed as time changed.

18
00:00:40,469 --> 00:00:41,874
Kay? That's going to be the number one rule. 

19
00:00:41,874 --> 00:00:43,503
That we're going to have to practice and be really carefully about

20
00:00:43,503 --> 00:00:45,204
Because it is very easy to say 

21
00:00:45,204 --> 00:00:48,610
Oh, that part of the graph she bounced. 

22
00:00:49,704 --> 00:00:52,848
Kay? No. Tell me how the graph shows distance changing

23
00:00:52,848 --> 00:00:55,470
verses time changing. That is the main and number one rule. 

24
00:00:55,470 --> 00:00:57,783
Then we're going to get into speeds. And learn to talk about

25
00:00:57,783 --> 00:00:59,220
-actually we'll talk about that when we get there. 

26
00:00:59,220 --> 00:01:02,204
But none the less, anytime you talk about what these

27
00:01:02,204 --> 00:01:04,268
are asking you to talk about

28
00:01:04,268 --> 00:01:06,143
always remember rule number one. 

29
00:01:06,143 --> 00:01:09,204
Kay? Everything is going to go back to rule number one. 

30
00:01:09,204 --> 00:01:11,628
So, and we'll get practice. We'll talk about it.

31
00:01:11,628 --> 00:01:14,393
But for now, I'll just let you watch the video once.

32
00:01:14,393 --> 00:01:16,204
And then I'm going to play it frame by frame. 

33
00:01:16,204 --> 00:01:17,954
Weee!

34
00:01:17,954 --> 00:01:19,688
[I want to do that.]

35
00:01:19,688 --> 00:01:22,001
I was telling Carlos, I'd be scared that I would bounce back

36
00:01:22,001 --> 00:01:24,969
and hit my head on the bridge. [You have a helmet on]

37
00:01:24,969 --> 00:01:28,063
[So?] Does he have a helmet on? [No.]

38
00:01:28,063 --> 00:01:30,594
[Well, normally you're suppose to.]
