How does a person standing on two feet increase stability?
ABy spreading the feet to widen the base
BBy keeping the feet tightly together
CBy raising the center of gravity
DBy standing on the toes of one foot
Answer & Solution
Correct answer: A. By spreading the feet to widen the base
1. Stability lasts as long as the center of gravity stays above the base of support.
2. Spreading the feet apart widens that base, so a larger lean is tolerated before tipping.
3. Bending the knees also helps, by lowering the center of gravity.
4. Standing on the toes of one foot shrinks the base to almost a point, which is far less stable.
