A local TV station in Orlando has done a study on exactly how many G-forces one experiences on some of the more popular and extreme roller coasters and other attractions in the Central Florida Attraction Zone. The report found that ‘The Hulk’ Roller Coaster at Universal’s Islands of Adventure theme park had not only highest G-force at 4.5Gs, but also had some of the most extreme changes in forces going from near 0Gs to 4.5Gs at one point.
Disney’s attractions came in at:
Space Mountain: 3.5 Gs
Big Thunder Mountain: 2.5 Gs
Rock n Roller Coaster: 4.4 Gs
Mission: Space: 2.1 Gs (but for 15 seconds in length)
Test Track: 2 Gs
