When the rate of onset of acceleration increases, it leads to a more rapid change in velocity, which significantly affects how the body responds to that acceleration. The human body has a threshold for tolerating acceleration forces, and when these forces are applied suddenly or rapidly, they can exceed the body's ability to respond or adapt.

The severity of the effects is primarily due to the G-forces experienced during this rapid acceleration. Higher rates of onset can produce greater G-forces that the body must endure, leading to various physiological responses such as G-induced loss of consciousness (GLOC), increased pressure in the vascular system, and potential damage to tissues and organs. This is particularly relevant in aviation and space contexts, where pilots and astronauts may experience extreme accelerative forces.

In summary, an increase in the rate of acceleration results in more severe physiological effects as the body is subjected to more significant forces in a shorter duration. This relationship underscores the importance of managing acceleration rates in environments where rapid changes are common, to mitigate risks and protect the body's integrity.
