In roller coaster design, what does "G-force" refer to?

G-force refers to the acceleration experienced by riders as a result of the forces acting on them during a roller coaster ride. When a coaster accelerates, decelerates, or changes direction, passengers feel a force that can be equal to or greater than the force of gravity. This sensation is what we refer to as G-force.

For instance, during a steep descent or a sharp turn, riders might experience increased G-forces that can create thrilling sensations, making them feel heavier or lighter, depending on the nature of the maneuver. Designers carefully calculate G-forces to ensure safety and an exciting experience, as excessive G-forces can lead to discomfort or injury.

Understanding G-force is essential for roller coaster enthusiasts, as it plays a critical role in the thrill and safety of the ride, helping to inform both design choices and rider expectations.
