The center of gravity of a body with a certain mass position is determined by its form, or the distribution of mass. The center of gravity, for example, is found in the middle of a uniform wire. However, if this wire is coiled into a circle, its center of gravity will be in the center.
State factor on which the position of the center of gravity of a body depend? Explain your answer with an example.
