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.
A point
Center of mass of an equilateral triangle is located at its geometric center (centroid).
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
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.
There are two major differences between "center of gravity" and "center of mass": 1) The term "center of gravity" aplies to the bodies with mass and weight, while the term "centroid" applies to plan areas. 2) Center of gravity of a body is the point through which the resultant gravitational force (weight) of the body acts for any orientation of the body while centroid is the point in a plane area such that the moment of the area, about any axis, through that point is zero. Center of gravity is the point at which a object can be suspended and be in perfect equilibrium
