Hello everyone! Today we are going to talk about friction. Friction is a force that happens between
00:00:00
two objects when they touch and you try to move one over the other one. For example, I have this
00:00:08
table that is soft and this car. If I push the car you can see how it goes very fast because this
00:00:15
surface is very very plain and soft but what happens if we do it over this tower
00:00:27
that is a little bit rougher than the table okay we put the car we push it with
00:00:37
the same force and you can see how it stops here because this surface
00:00:48
is rougher and it makes the wheel just go slower and slower till the car stops.
00:00:55
We can find this force also in the daily life. For example, this is a
00:01:03
normal sock, you can see it's a normal one, and this one are the ones that my
00:01:14
kids use when we are at home and you can see these small spots made of plastic
00:01:22
that are thought to avoid slip and slide when we are walking okay with this one you can just
00:01:33
slip and fall, sorry, but with this one you won't, because you are like stuck to the floor,
00:01:44
okay, and I hope you understood this, if you didn't just ask me by email and I will look
00:01:59
for a way to explain this better, okay, bye bye.
