00:00:08,934 --> 00:00:10,237
- How'd it go?

3
00:00:13,010 --> 00:00:14,514
- I've got to do a make-up exam.

4
00:00:24,812 --> 00:00:28,113
- Leykin, hey, Leykin!
- What do you want?

5
00:00:28,317 --> 00:00:33,160
- Leykin, may I help you prepare?

6
00:00:34,510 --> 00:00:36,830
- Uh-huh...
- That's wonderful!

7
00:00:37,044 --> 00:00:38,238
We'll start tomorrow!

L. GNILOVA, A. VLASOVA

13
00:01:35,625 --> 00:01:39,082
- Let's begin with physics.
From the parallelogram of forces.

14
00:01:39,308 --> 00:01:41,361
Leykin, write down the task conditions.

15
00:01:41,653 --> 00:01:44,317
Let's suppose that a body is being
acted upon by two forces

16
00:01:44,464 --> 00:01:46,874
from different directions
at an obtuse angle.

17
00:01:47,708 --> 00:01:51,031
- "Obtuse"... Look at yourself!

18
00:01:51,292 --> 00:01:54,065
- The first force is equal to...
Leykin, are you writing?

19
00:01:55,368 --> 00:01:58,040
- Force... Vector...

20
00:01:58,548 --> 00:02:01,407
Force is something to reckon with!

21
00:02:17,427 --> 00:02:20,166
- Leykin! Are you ready?
Go answer.

22
00:02:25,764 --> 00:02:27,565
- Hurrah! Recess!

23
00:02:57,682 --> 00:02:59,532
- The lesson is starting!

24
00:03:05,042 --> 00:03:06,720
- If there was no slide...

25
00:03:08,747 --> 00:03:09,321
RESISTANCE FORCE OF SLIDE

26
00:03:09,486 --> 00:03:13,458
- ...you would fall down
like Newton's apple.

27
00:03:16,214 --> 00:03:18,522
At the same time,
the gravitational force

28
00:03:18,809 --> 00:03:22,426
lets you overcome the frictional
force of the slide surface

29
00:03:22,678 --> 00:03:25,607
and descend along the inclined
plane into the water.

30
00:05:26,884 --> 00:05:31,537
- To make the parallelogram
of forces clearer for you,

31
00:05:31,724 --> 00:05:32,800
here is what we shall do:

32
00:05:33,235 --> 00:05:36,847
Let's substitute the force of gravity
with the force of wind pressure.

33
00:05:38,892 --> 00:05:41,700
SAILS

34
00:05:59,153 --> 00:06:01,559
WIND

35
00:06:01,773 --> 00:06:02,969
TRACTION

36
00:06:04,059 --> 00:06:05,509
HEADING HEAD TO WIND

37
00:06:05,510 --> 00:06:07,595
HEADING CLOSE HAULED

38
00:06:08,597 --> 00:06:09,309
PORT TACK

39
00:06:09,412 --> 00:06:10,453
STARBOARD TACK

40
00:06:10,479 --> 00:06:11,415
PORT TACK

41
00:06:13,445 --> 00:06:14,810
HEADING STERN WIND

42
00:06:23,025 --> 00:06:23,984
RECESS

43
00:06:24,193 --> 00:06:27,059
- So, did you understood
what I told you about the sail?

44
00:06:39,602 --> 00:06:41,382
- What the frig do I need sails for?

45
00:06:46,780 --> 00:06:48,175
BUOYANT FORCE

46
00:08:05,847 --> 00:08:07,999
- I told you that the
sail is more reliable!

47
00:08:08,898 --> 00:08:10,988
- Some champion you are!

48
00:08:33,576 --> 00:08:39,115
"On the isle of Little Cayman
is buried a treasure".

49
00:08:39,718 --> 00:08:40,193
- Oho!

50
00:08:53,438 --> 00:08:56,004
- Enough physics!
Let's learn some geography!

51
00:08:56,550 --> 00:08:59,918
- Enough for today.
We'll study geography next week.

52
00:09:03,830 --> 00:09:04,976
