G Forces!

lol "Centripital" lol!

Centripetal force is not the same thing as Centrifugal force.

actually, i think this ride is going to be one big flop. The launch is gonna blow, the top hat is going to be unimpressive, and the 270 degree turn to the finish, BORING! Because we all know Cedar Point has a reputation for making rides that are no fun at all.
Dont expect me to waste my precious moments of life riding the worlds tallest and fastest roller coaster.

How is being launched at 120+mph going to blow? And how is being 400 feet in the air unimpressive? What reputation are you talking about? CP rarely makes rides that are no fun.

Example of Centripetal force- the force of a wall on a rotor ride pushing inwards on you.

Example of centrifugal force- the percieved force of you pushing on the wall of the rotor (which is not actually happening, the wall is changing your direction constantly creating a constant acceleration towards the center of the ride)

The only one of the two that actually exists is centripetal, centrifugal is only "imaginary."

Just a minor note, I think some people in here are confusing accelleration g's(the kind that push you into the back of your seat) and vertical g's(the kind that pull you towards the bottom of your seat). The accelleration g's experienced on the launch won't be nearly as high as the vertical g's experienced on the pullup and pullout. Hopefully this will clear some things up, and for the people who were aware of this please don't flame me because I insulted your superior intelligence.

Enjoy your ride on the Big Bad Bug

LOL very good Mantis Man, you done and told em what i was gonna say. Steelrider33, Okay...... do somemore research and try to not hit your self too hard when you find out how many Gs most coaster pull. You have never been to cedar point have you? Where oh where do they have a rep for building "No Fun" coasters. When you grow up, you will grow to like those big rides and not make excuses for not riding them.

If the radius of the pullup/pullout is 200 feet (the 90 degree twists starts at 230 feet as stated on the official site, and we'll say that it starts 20-30 feet off the ground), then the maximum Gs that I calculated were around 4.8 g. That would be going 120 mph through a circle with a radius of 200 feet. Whatever it is, you know it will be under 5...

Blonde, Are We?

Some people need to go to howstuffworks.com\roller-coaster.htm and read up on g-forces before they post their idiotic opinions in this thread.

go to RCDB.com they will give u the g forces of coasters

12-18 G's? Are you crazy?

I am not a physist however I was just thinking of the G-forces that a football player endures when being tackeled, I read somewhere that its in the vicinity of 10-15 G's. I could be wrong so please flame me if I am.

G forces are all about duration. Most people can easily handle 2 or 3 g's for quite a long tine. The higher the G force, the less number of people can handle them for long periods of time. Most G forces of any significance on roller coasters last under 1 second. If the G's last under 1 second, it won't hurt you unless it's a bizarre such as a car accident can pull several hundred G's for a few micro-seconds. Even if high G forces last longer than one second, all it really means is your brain isn't getting oxygen. Even if a roller coaster pulls 8 G's, it will take a while before ANY brain damage occurs. At the most of any coaster that sustains high G forces, none are any where near the point of brain damage. If you black out, it means your brain isn't getting enough oxygen, It basicly shuts down to protect itself. Except in rare cases of people coming out of freezing cold water after 30 minutes alive... Your brain can handle a lack of oxygen for about 2 minutes without any permant damage, I believe that it takes about 5 minutes without oxygen before you become brain dead. If your anywhere in the middle of there, you do sustain irreversible damage. No roller coaster goes anywere near the point of brain damage.

Chocolate is chocolate, but liquor is quicker.

to clear something out the duration of g-forces is a major factor if they're harmful or not. for example texas tornado formally at SF astroworld pulled 6.5Gs, but only for a second. now jet fighters who need the g-suits. if they go into a immelman manuever they could be pulling 7 Gs or more for a long time depending on how fast and how tight their pull out is.
