00:00:01.639 --> 00:00:04.589 A:middle L:90%
this question asks us about motion problems, so let's
2
00:00:04.589 --> 00:00:09.009 A:middle L:90%
quickly define what that means. All motion problems will
3
00:00:09.009 --> 00:00:16.370 A:middle L:90%
discuss a distance, the time and the rate,
4
00:00:17.289 --> 00:00:20.109 A:middle L:90%
which represents the amount of distance covered over a certain
5
00:00:20.109 --> 00:00:23.760 A:middle L:90%
time. And as we can tell, these three
6
00:00:23.760 --> 00:00:26.969 A:middle L:90%
are all quite related. So the main difference between
7
00:00:26.969 --> 00:00:29.760 A:middle L:90%
the problems offered earlier in the textbook and we've seen
8
00:00:29.760 --> 00:00:33.270 A:middle L:90%
in this section is simply which variables were given on
9
00:00:33.270 --> 00:00:37.079 A:middle L:90%
how they're used. Each of these three variables will
10
00:00:37.079 --> 00:00:40.020 A:middle L:90%
use velocity to represent. Rate here can be used
11
00:00:40.020 --> 00:00:41.979 A:middle L:90%
to find the other ones. As we can see
12
00:00:41.990 --> 00:00:45.799 A:middle L:90%
the rate musical to distance over time. And using
13
00:00:45.799 --> 00:00:48.429 A:middle L:90%
this expression we can see it at the time is
14
00:00:48.429 --> 00:00:52.289 A:middle L:90%
equal to the distance over the rate and the distance
15
00:00:52.299 --> 00:00:55.549 A:middle L:90%
is equal to the rate times the time. So
16
00:00:56.030 --> 00:00:58.729 A:middle L:90%
different types of motion problems will give us different tools
17
00:00:58.729 --> 00:01:02.369 A:middle L:90%
to work with. However, in the end,
18
00:01:02.719 --> 00:01:04.439 A:middle L:90%
we're always using the same types of techniques to manipulate
19
00:01:04.439 --> 00:01:07.540 A:middle L:90%
these variables and were to acquire whatever unknown variable we're
20
00:01:07.540 --> 00:01:10.930 A:middle L:90%
looking for, whether it's the distance, the rate
21
00:01:11.000 --> 00:01:11.750 A:middle L:90%
or the time
