WOW Physics lecture!!! there wasn't this much discussions in my Physics tutorials @ uni.... u guys are very keen young scientists aye? good work seiko u mad scientist :)

Now for a discussion on Quantum Physics and String Theory :kuda:
Who's up First?

Schrödinger's cat was gay!!

does that count as a contribution??

Wait one moment ! :lol:

Since the guys arse is not moving relative to the seat, there must be an equal and opposite force produced by the seat to get a net force of zero thus no motion of his arse (3rd law) so the seat is push back just as hard as his arse is push the seat.

If you regard the dude on the bike as a separate body before the corner, when he turns the separate body wants to go straight (so does the bike, thats where the forces at the wheels come in) but the bikes in his way and you get his arse pushing up against the bike and your force.


Anyway, im pretty sure everyone knows how it works in real life its just complicated with the god damn terminology

Not applicable here.
Would you expect a bullet you fire at a wall to come back at you at the same speed at which it hit the wall?
C'mon!!!
It's Quantum Physics time :kuda:

no becuase if wall and bullet both produce equal and oposite forces then net force is 0, so no motion. What you are suggesting is that the wall produces twice the force of what the bullet does on impact.

What I am suggesting in a roundabout way is that the Debate is over.
The fact that we have been debating a guy's arse is what is keeping me awake nights now!
Ok the seat pushes back at the same equal force if that makes you happy, if it didn't resist the downward motion he would keep going down through the bike and onto the the road and then we would be discussing the Phillidelphia experiment and Temporal Displacement.
Matter, Anti-matter, Warp Coils, Photon Torpedoes, Phasers, Timelords etc etc etc :lol: :kuda:

Anyway after all this shit, I'm going on Holiday Travelling through Time and I'll be back Last Week!!!!!!!! :shock:

its because he's got a piece of buttered toast stuck on the bottom of his bike and a cat strapped to his helmet

TWO POINTS.
1. On one of the main discussion points there's a fallacy.
The seat (the whole bike) actually pushes his arse (his whole body) towards the inside of the corner MORE than his arse pushes the seat out. If it were the same his arse would travel in a straight line and not go around the corner.

2. He doesn't fall off because he's a skilled rider EXPERTLY UTILISING the above science and modern bike technology!
:kuda:

Centripetal and centrifugal are equal and opposite forces as described in Newton's third law.
Centripetal force is the force that is directed radially inward, towards the center of a circular path when an object is undergoing circular motion.

Kev here shows the classic outside knee not gripping, have a look at the position on his right foot & that shows just how twisted the outer leg can end up 8)

Use the Force Kev!!! starwars

I thought I would throw this in for good measure ;)
