Hello boys and girls! Today we are going to talk about how machines and tools work.
00:00:00
Some tools and simple machines, remember that simple machines are the ones that have only a few pieces, need our energy to work.
00:00:13
Energy of people. For example, we can turn on and off something, we can twist something, we can push something or we can pull something.
00:00:25
On the other hand, many complex machines, remember that complex machines are the ones that have lots of pieces, need energy from two different things.
00:00:56
Some of them need energy from batteries, but some other need to use mains energy.
00:01:09
To use mains energy we need to have some of these things at home.
00:01:26
We need to have a socket, we need to have a plug, we need to have a switch and we need to have a cable.
00:01:33
Ok boys and girls, I hope you understand everything, so see you soon!
