supposivly hes done this 90 to 270, wheres the vid? yes i did search for it. and soory i dont want to bring up this controversy about cork 1s and 90 to 270s again. looking for the video, if 1 even exists??
hey. you know whatd be fun, lets have that argument again.
no he didn't break the laws of physics.
Heloo, my name is Shane Mckonkey. I was born in Vancouver Canada, thats aboot three hours north of, ah, seattle.
Right now were here in Bella Coola Canada, and ah, weve been shut in by the weather for like three weeks eh. We havn't shot fuck all. Ooh, Soory.
We've just been sittng around, eating pasta, and spending loonies and toonies on Kokanee and peelers.
But, as soon as this weather clears, im gunna pull on my toque, eat some canadian bacon, and ah, im keen to giver.
who says he isn't touching anything? air is made out of molecules so he's touching air, just a matter of putting more force by "pushing" the air into the other direction then the spin... action-reaction. If he wasn't enable to do this a plane wouldn't be able to fly.
but i figure this discussion has been here before so just ignore ^
no no no i want the actual law as it is stated
and since no one else wants to do it, i will. i believe the law we are dealing with here is rotational inertia which is:
A rotating rigid body maintains it's state of uniform rotational motion. It's angular momentum is unchanged, unless an external torque is applied.
In that video Pep applies an external torque and is also not a rigid body, no law has been broken. There are also other things to consider like air resistance.
I don't think it has much to do with air resistance. I think that if you spin your arms in one direction, you will move the other, like when people are about to fall, they have the tendency to spin their arms really fast in the opposite direciton they're falling. You've seen it. Like when people get scared on big tabletops, they spin their arms.
Don't underestimate air resistance. I'm a skydiver, and we use nothing but air and our body to control our movements, and we can go from left spin to right spin very fast. It's not completely the same as what pep does here because we use the speed (+-200km/h) of freefall (and our body) to manouvre, but it's because of the air we can do it.
well it was a 22m jump therefore at the speed he is going at there has to be some air resistance. this air resistance acted as the object he touched in order to spin the other way. beleive me ive thought about this for a long time and this seems like the answer
It is not air resistance. The guy that used the flailing of arms is spot on. Another analogy is jumping on a dirt bike. If you give the bike gas while is the air the rear wheel will spin forward. This causes the reset of the bike to spin backwards, because as we all learned in physics, Every action has an equal and opposite reaction. If you hit the rear brake while in the air the rear wheel comes to a sudden stop and the inertia of the wheel rotating forward is transfered to the bike and the bike rotates forward. What I am trying to say is that by throwing body parts around, like pep did, you can change the direction of your rotation.
