X- The Fastest Coaster with Inversions

Wednesday, November 6, 2002 10:58 AM
Is X the fastest coaster with an an Inversion? The RCDB lists the top "ten" speeds are on inversionless coasters, and X comes close.

-----------------
Sure, coasters have good negative Gs, but telekinetics do it better.

Either X or Sonny.

Each has around a 215 foot drop right?

Taking bets on how long it'll be before someone decides to call the overbanked turns on MF "inversions."

Son of Beast.... I expected a steel... according to RCDB Sonny wins it.

Sonny actually dose faster than it's design speed by about 2-3mph on good days.

The trains turned out heavier than anticipated. It has been clocked at 82mph

Design speed was for 78mph (Main drop) Second drop 67mph and loop drop 62mph.

Chuck, who even got the latteral air on the loop drop, in the backseat sunday that has been missing for over a year :0)

P.S. Beast also hit 70mph at one time (Under SPECIAL Conditions) Very special.

No Millennium Force is the tallest coaster with inversions, they just call them over-banked turns. :) I'm just kidding

Special conditions: High tailwind and a boatful of hefty ACE members? ;)

Kidding of course. (since I'm an ACE member.)

The Beast can hit 70 if the trims aren't used at all.

SoB is deffinately the fastest though.

70mph with track greased HW insane style, And a trainful of no less than 200 lb. people.

Chuck, who is told that normal top speed of Beast is around 58mph now.

When the sheds brakes are not on or very light, The Beast top speed is reached in the third corner following the second tunnel (The one made out of two connected by wood) The ride constantly builds speed untill that point with only one major loss. (The hill comming out of the valley)

Weight (mass) has no effect on the final velocity of a roller coaster train. Only momentum is changed, and that makes a difference with windy conditions, track friction etc. If you look at the formula for Final Velocity, it does not include mass in it at all. they could be 200 lb people or 500lb people and the speed would be the same under the same conditions.

That isn't true. The train gets a certain amount of potential energy (mgh - m for mass!!!). Almost all of that is then converted to kinetic energy at the bottom of the hill, which you can then use to calculate the speed. Mass won't affect it much, but it does affect it.

ms696969, you're right, but completely off. The formula for kinetic energy is (1/2)*m*v^2, so mass just cancels out the m that is in potential energy. While in a vacuum an object's mass has no impact on velocity, in the real world there are numerous variables which must be considered, many of which involve mass of the rider.

yeh, i know kinetic energy is 1/2mv^2 - i just had to point out that weight affected it so said potential energy instead.

Well, actually, that's not the case.

mgh = potential energy

1/2mv^2 = kinetic energy

So, if all of your potential is converted to kinetic energy;

mgh = 1/2mv^2

m = mass, and it falls out of the equation. Mass does affect the speed of a roller coaster, and everything else on the planet, though, because of losses.

friction = (mu)(Normal force)

The normal force is the mass*force of gravity*the sin or cos of any angle the object may reside at. So, the heavier an object is, the larger its Normal force - thus, higher losses to friction.

Of course, I go to a research university, and they don't teach us how to apply things to the real world. But, I think this means - in some twisted sense of logic, that the steeper a drop is, the faster a coaster will go ;)

I know it's not perfectly, true. . . we'll call it Fuzzy Physics, okay?

Exactly, i know that in a vacuum mass doesn't matter, but on the earth where there is friction it will affect. I just done this subject in maths, about objects on slopes. I therefore know that it does affect it, though very little.

The Steel Phantom was the fastest looping coaster, there isnt any arguing that...and if it was still here today it still would be. It topped out at 80 or so MPH I believe.

Wasn't there a huge debate a while back that proved it doesn't matter how steep a drop is, the speed will remain the same....
