Hi! Now, I want you to think about the difference between these four means of transport. 00:00:00
This is a cart, this is a carriage, this is a state coach, and this is a mobile hub. 00:00:08
Let's start with a car. 00:00:20
At the beginning, people used the energy from their hands and legs to transport objects from one place to another. 00:00:23
Then, they started to use the energy from animals, in this case the horse, to transport objects from one place to another 00:00:41
and they could travel longer distances, they could transport more goods and people 00:00:55
because they have more energy from the animals to move the stage coaches. 00:01:16
and nowadays with mobile homes we can go from one place to another we can place from one 00:01:29
country to another and this mobile homes uses the energy from 00:01:40
do you know the answer? does it use the energy from people? 00:01:52
No. Does it use the energy from horses? No. This mobile home uses the energy from 00:01:58
burn fuel. Hi again. Let's have a look at this other machine. It's a pirate ship. 00:02:10
Can you see it? This machine works. What do you think? With the energy from 00:02:24
electricity? With the energy from burn fuel? Or with the energy from the wind? 00:02:36
Right? This ship works with the energy from the wind and we can also see a 00:02:44
different machine on this ship look here we have wheel and a rope and you see it 00:03:09
at the end of the rope there is an anchor if we turn the wheel on one 00:03:20
direction the anchor rises if we turn the wheel on the other direction the 00:03:31
The anchor lowers, the catapult, the ussertower, and the anchor system are all based on simple 00:03:41
machines. 00:03:57
See you soon! 00:03:58
