High-magnitude acceleration is defined as G-forces that exceed 10 G's and are of short duration, typically lasting less than a second. This definition is based on the physiological effects experienced by individuals subjected to such extreme forces, often encountered in specific aviation or aerospace contexts.

When G-forces surpass the threshold of 10 G's, they can lead to rapid changes in physical states, impacting the body significantly, especially if the acceleration is sustained for durations longer than a second. The brief nature of this acceleration is also crucial, as it allows for extreme force to act on the body without leading to prolonged stress that could cause severe injury or loss of consciousness.

In contrast, other definitions related to G-forces that involve lower thresholds or longer durations may not qualify as high-magnitude acceleration, as they do not reach the intensity necessary to elicit the same physiological responses. For example, G-forces lasting longer than 2 seconds can lead to different types of tolerance issues and symptoms, complicating the body's ability to adapt.
