Definitions for "G-force"
Gravitational force that holds the sled and athletes on the wall of a banked turn. A "G" is equal to the force of gravity. On some tracks, the G-force exerted on an athlete can exceed five Gs. That would make the athlete feel like he or she weighed more than five times their actual weight.
The measure for lateral acceleration, or "road-holding". One G is equivalent to 32.2 feet per second, the rate at which any object accelerates when dropped at sea level. If a car were cornering at 1.0 G: a figure that very few production cars are able to approach: the driver's body would be pushing equally hard against the side of the seat as against the bottom of it.
the greatest gravitational force experienced during the ride.
