Final answer:
The body's ability to maintain stability is governed by principles such as the center of gravity, base of support, and lowering the center of gravity.
Step-by-step explanation:
The body's ability to maintain stability is governed by several principles. One important concept is the center of gravity (cg), which is the point where the body's weight is evenly distributed. For stability, the cg should be above the base of support, which is the area between the feet.
Another principle is expanding the base of support, such as by spreading the feet apart, which increases stability. Lowering the center of gravity, such as by bending the knees, also increases stability. These principles help humans maintain stability and prevent falls or accidents.
