There needs to be a lecture on how to do that chalk thing...

[Cifrocco]

"It's non-negotiable!"

[acetote]

WHY sometimes upper &sometimes lower string were broken

[thespetnaz101]

i used this vid to play snakes!

[perepe10]

the string that breaks depends on how he pulls it, when he does it fast the bottom one breaks, and when he does it slowly, the top one breaks, so he wanted the girl to be happy and he broke the one she said XD

I suppose that 12 years later is too late to say this... XD

[LanRous]

[AlohaBay]

Jeez that thigh massage video is such a distraction...

[KimmyJRapeAllDaNoob]

@AlanKey86 why would it be inconsistent? The normal force is in the opposite to the applied force. that force can change. the third example shows the applied force to be his hand pushing against the wall. the wall pushes back with an equal and opposite normal force. if it did not, then his hand would go through the wall.

[AlanKey86]

At 15:04 he states that when sitting on a seat, you are pulled down (by gravity) and the seat pushes back (contact force). This seems to be inconsistent with the further 2 examples he gives. Or have I misunderstood?
