Hi! Now, I want you to think about the difference between these four means of transport.

2
00:00:08,939 --> 00:00:20,829
This is a cart, this is a carriage, this is a state coach, and this is a mobile hub.

3
00:00:20,829 --> 00:00:23,829
Let's start with a car.

4
00:00:23,829 --> 00:00:41,340
At the beginning, people used the energy from their hands and legs to transport objects from one place to another.

5
00:00:41,340 --> 00:00:55,340
Then, they started to use the energy from animals, in this case the horse, to transport objects from one place to another

6
00:00:55,340 --> 00:01:16,219
and they could travel longer distances, they could transport more goods and people

7
00:01:16,219 --> 00:01:29,219
because they have more energy from the animals to move the stage coaches.

8
00:01:29,219 --> 00:01:39,459
and nowadays with mobile homes we can go from one place to another we can place from one

9
00:01:40,819 --> 00:01:51,060
country to another and this mobile homes uses the energy from

10
00:01:52,980 --> 00:01:58,969
do you know the answer? does it use the energy from people?

11
00:01:58,969 --> 00:02:10,409
No. Does it use the energy from horses? No. This mobile home uses the energy from

12
00:02:10,409 --> 00:02:24,210
burn fuel. Hi again. Let's have a look at this other machine. It's a pirate ship.

13
00:02:24,210 --> 00:02:36,039
Can you see it? This machine works. What do you think? With the energy from

14
00:02:36,039 --> 00:02:44,139
electricity? With the energy from burn fuel? Or with the energy from the wind?

15
00:02:44,139 --> 00:03:09,060
Right? This ship works with the energy from the wind and we can also see a

16
00:03:09,060 --> 00:03:20,379
different machine on this ship look here we have wheel and a rope and you see it

17
00:03:20,379 --> 00:03:31,229
at the end of the rope there is an anchor if we turn the wheel on one

18
00:03:31,229 --> 00:03:41,159
direction the anchor rises if we turn the wheel on the other direction the

19
00:03:41,159 --> 00:03:57,520
The anchor lowers, the catapult, the ussertower, and the anchor system are all based on simple

20
00:03:57,520 --> 00:03:58,520
machines.

21
00:03:58,520 --> 00:03:59,879
See you soon!
