What is an example of 'vertical' G forces?

Vertical G forces refer to forces acting along the vertical axis of the body, which can significantly impact how a person experiences motion and gravitational pull. An example of vertical G forces is falling from a height. When an object or person falls, they experience acceleration due to gravity, which creates vertical forces that can be felt in the body as it accelerates downwards.

In this scenario, while falling from a height, the individual experiences an increase in the effects of gravity as they descend, leading to a distinct sensation of weightlessness at the peak of the fall followed by a sudden jolt upon impact or deceleration. This direct influence of gravity in a vertical direction is the essence of vertical G forces.

The other situations presented do not primarily illustrate vertical G forces. For instance, acceleration during takeoff primarily involves horizontal G forces, while turbulence involves irregular vertical air movements but not sustained vertical acceleration associated with gravity. Being T-boned in an accident may involve sudden lateral forces but does not convey the same vertical G force experience as falling does.
