How does gravity affect people riding roller coasters?

Answer 1

Gravity affect people on 6 axis. They are positive or negative x (lateral G's), positive or negative y (vertical G's), and positive or negative z (acceleration G's). Vertical G's When on a traditional coaster (rider is sitting in an upright facing forwards), vertical G's act on the rider up and down. When vertical G's are positive, they make the rider feel like he/she is being pushed into his/her seat. When negative vertical G's are present, they make the rider feel weightless, or even give people that "Stomach in your throat" feeling. Lateral G's When on a traditional coaster (rider is sitting in an upright position facing forwards), lateral G's act on the rider left and right. Positive lateral G's make the rider feel like he/she is being pushed to the right, and negative lateral G's make the rider feel like he/she is being pushed to the left. Acceleration G's When on a traditional coaster (rider is sitting in an upright position facing forwards), acceleration G's act on the rider forward and backwards. Positive acceleration G's make the rider feel like he/she is being pushed forwards (like quickly speeding up in a car; mainly felt on Roller Coasters with launches). Negative acceleration G's make the rider feel like he/she is being pulled backwards (mainly felt on the brakes of a roller coaster when decelerating)
