Ok, Starvin Rocker......... the cars were travelling counter clockwise at Matchams, but no one can tell me WHY

Ok, since you called me out! (Actually, I'm flattered) \nMatchams appears to be a road course and perhaps the design of that road course was for the Karts to run counter-clockwise. It's just the way it's done over there. For example, why does water in toilets swirl the opposite way in the Southern Hemisphere than it does in the Northern Hemisphere? WHO KNOWS??? It just is the way it is.

Usually magnets or wedges that are pressed down inbetween two metal rails:\n\n&#92;/\n||\n\nSorry that i couldn't draw well via the keyboard, but imagine the above as a cross section of the wedge, and the lower vertical lines as a cross section of the metal or semi-metal rails...the rails can taper outward a little to create more surface-to-surface contact.  you can imagine the normal force exerted onto one another between the wedge and the rails as the wedge is pushed into the rails, this normal force grows fast quickly as more force is exerted onto the wedge.  and i'm assuming that you're taking or have taken physics courses, so you should know that let's say a box sliding on the floor, has a frictional force of kw, where k is the kinetic friction constant, and w is the weight of the box, for the wedge/rail setup, we would replace w with the normal force, and the equation wouldn't be that simple, in fact, the force would grow almost exponentially as more force is exerted downward on the wedge since the wedge gets wider and wider.  think of it as a brake/rotor setup on a car, but instead of circular, it's linear, and instead of the brake pads squeezing on the rotor, it's the rotor being pushed into the pads.  this similar setup is used on trolley cars, which is why on some trolley trails, you see another pair of rails, situated close together, inbetween the two main rails for the wheels.\n\nnow in an emergency, there is no stopping anywhere else on the roller coaster track except on the boarding/exiting platform.  the engineers made it so that the momentum of the cars will take them through the entire track system no matter what the (realistic) load distribution is.  can you imagine trying to stop an extremely fast set of attached cars on a track with twists, turns, and loops?  and on top of that, the decision when and where to stop the cars is left to some teenage kid in the booth?  very unsafe and unreliable.

The KE of the moving vehicle is dissipated as heat in the brakes as the brakes use friction.\n\nThe answer to your second question is that no work has been done and therefore there has been no change in KE.\n\nIn terms of transfer of momentum, the really huge ball called the earth and the car did interact.  If the car started out going West and then ended up going East, the total momentum (angular and linear) between the car and the earth must be conserved.  This means that the earth was caused to change its rotation when the car turned around.  Obviously, the earth is so much bigger than the car that you don't even notice the change in momentum of the earth.

its supposed to look like a sideways heart.. the more 3's are more hearts..

A mag-levs route is lined with magnets and they use the polarity to move -- almost like a model or toy train; except this is done with magnets. They don't come in contact with anything though they do have retractable rubber wheels but those aren't used when they are moving.\n\nEDIT: P.S. Aproov -- anyone can copy and paste...\n\nThere's more info in the below link:

All planets are tilted, just not to that extreme...   It is more than likely that it had a close encounter with a large object in its past.  But what the crap do you mean that it moves sidewards?  Its in a relatively normal orbit, how does it move sideways?  I think a more interesting question is why does Venus spin clockwise?

Wow...how is that possible.when i move back and foward it starts going in circle...its really cool.

Dear Lord,\n\nPlease help me circle the wagons!  There is no parallel for my situation.  I'm surrounded by squares who will ace this test and I forgot to study a segment.  Be my ray of light, beaming through a kite of confusion.  Send down your angles to assist me.  I need points on this test.  Please, send me a sine.

b/c with two right wings you keep going in circles

As kind of a play on the Slug Bug game, my sister and I invented Cadillac Smack. We just hit each other whenever we see any type of cadillac, because we just didn't see enough volkswagons to satisfy our desire to hit each other. \n\nAlso...naked twister. But I am sure someone else has come up with that before lol.

WOW!  I can not believe that one has answered this question correctly. Internationally this was the Brits fault because of the breeze off the ocean most runners wanted the wind at their backs. Since the markings for exchange zone have to be consistent for any type of state, national or World records all the tracks have to marked the same way, thus all are now like the Brits with the wind at their backs.    Now all track marking and exchange zones are set for counter-clock wise running.

Except for stars nearest the Pole Star, all stars move in one single direction all the time --- east to west. This isn't because the stars are moving but instead because Earth is rotating.\n\nIf you're seeing stars moving 'rapidly' and 'sporadically' you're either not observing stars, or you should tell me where you're gettin' that good stuff :)

Perhaps they can't tell which direction the emergency vehicle is comming from? It is best to stop than to be a moving variable. \n\nI always pull to the right to make way for the emergency vehicles, and I will also use the left lane to make more room for police vehicles on the shoulder while they are ticketing someone. I do this also for cars on the shoulder who have hazzard lights on.\n\nI also will flash my brights to alert semi tractor trucks that their haul clears my front bumper if they are signaling to pass. and flash again if they are trying to merge into traffic. this really helps them take the guess work out of clearing the bumper.

scodallaro doesn't know what he's talkin' about. on a 2 tire pit stop it's the right side tires that are changed 99% of the time. so i guess that would be the outside.

Think of the wheels as spinning masses or revolving weights, in fact gyroscopes. \nEach wants to turn left or right while spinning but is constrained by it's axis,\nHowever both drift overtime.\nNow add another pair further back and wider apart, and this pair are not on the same line of travel.\nWith four wheels all wanting to drift the resultant direction becomes a straighter line.
