Tbh this is such a bad demonstration. Well what I think is, if both cars have a crumple zone, then it should has a less impact force. But if u are assuming the surface of both cars behave exactly the same as well then it wouldn't make a difference, as velocity depends on the frame of references
no, combined impact sped is 100 but the forces are equally shared between 2 vechicles. so the impact damage shoudl be similar to each car doing 50 into a wall...
@@yandyyay you are wrong, and seem to be assuming that energy scales linearly with speed, which it does not. Doing 100mph into an immovable object which absorbs no energy will result in all the kinetic being absorbed by 1 car instead of 2, resulting in 'twice the damage'. However, to achieve similar impact damage, you need to half the kinetic ENERGY, not the speed. E = 1/2 mv^2, so do the math...
@@yandyyay we shouldnt question him maybe he is always right so he always makes all the right decisions and says the correct things, we should strive to be like him, we can only envy that he has his entire life right and without problems he cant correct
I’m so far from understanding Physics but I cracked up at the worst scientific testing ever at the beginning. Hilarious 👍
this teacher is a joke, and is wholly underqualified to teach even 5th graders...
Yeah
I like it! 👍

I don't understand. When you hit the wall, the forces doesn't equally share between the car and the wall? It's the same case, isn't it?
@@vojtareichl not. If the wall is an immovable le object

@@GamezGuru1 right ypu do.... so the scientists and mythbusters and actual evidence from actual real world crashes are all wrong ?
