The center of mass of a sphere is its geometric center.
A point
Center of mass of an equilateral triangle is located at its geometric center (centroid).
In both cases, because of their symmetry, the center of gravity is in the geometric center.
If the cube is uniform ( ie it has uniform density) then the geometric center of the cube is its center of gravity.
The center of mass of a sphere is its geometric center.
The center of mass of a soccer ball is its geometric center.
It is a geometric ratio.
The geometric center and the center of mass of the Earth are essentially the same point.
Center of mass of an equilateral triangle is located at its geometric center (centroid).
A point
No, the optical center of a lens is the point on the lens axis that is unaffected by refraction, while the geometric center is the physical center of the lens. The two may not coincide depending on the shape and design of the lens.
In both cases, because of their symmetry, the center of gravity is in the geometric center.
circle
The center of the solar system is called the Sun. It is a star located at the heart of the system, around which all the planets, including Earth, revolve.
If the cube is uniform ( ie it has uniform density) then the geometric center of the cube is its center of gravity.
All points equidistant from a center point.
