The g-force experienced by an object is its acceleration relative to free-fall. One ‘g’, is equal to 9.806m/s (or approximately 10m/s). The g force is classified as acceleration imposed by Earth’s gravity. A force of 7G, for example, means that an object is accelerating at seven times the force of gravity.

a unit of force equal to the force exerted by gravity; used to indicate the force to which a body is subjected when it is accelerated

Unit of measurement used to describe lateral acceleration generated while the vehicle is driven in a steady state turn on a skid pad circle. An average sedan generates 0.60 G of lateral acceleration. Measured in "gravities", one G equals the earth's gravity at sea level.

The apparent increase in weight of an object due to gravitational forces. Centrifugal force is a type of g-force which keeps your clothes stuck to the outside of a spinning washing machine! In racing cars, it is the force pulling the drivers head to one side as the car corners.

The gravitational force that holds both the sled and the athlete against the wall on a banked turn.

A force caused by acceleration expressed in g's.

the force of gravity. Acceleration or deceleration is often expressed in Gs, representing the added "gravity" force acting on a body. If someone weighed 100 lbs. at rest, and experienced a force of 3G acceleration, they would experience the feeling of weight of 300 lbs. Tissues of the body have tolerance limits to G forces, and these limits are known.

Gravitational acceleration of a freefalling body. Equal to 32.2 ft/sec2.

The force that is exerted on a vehicle during acceleration, deceleration, or cornering, expressed in units of gravity (g's).

A physical force equivalent to one unit of gravity that is multiplied during rapid changes of direction or velocity. Drivers experience severe G-forces as they corner, accelerate and brake.

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.

the force of gravity, or an equivalent tugging resulting from a vehicle’s acceleration.

This is most noticeable as a driver goes round a fast corner, his head can be seen tilting away from the direction of the corner. This is the centrifugal effect, G-force, pulling the drivers body away from the corner.
