It is easier to stand on two legs than to stand on a single leg. Why? |
| Answer» Solution :A body REMAINS in stable equilibrium when the vertical line through its CENTRE of gravity remains well within its base. Equilibrium is disturbed when this vertical line falls outside the base. It is difficult to maintain the vertical line passing through ONE foot only. This reduces the stability while standing on one leg. Standing on two legs increases THEBASE area through which the vertical line is more likely to PASS and hence a higher stability of equilibrium is achieved. | |
