The point through which the resultant of all gravitational forces acting on the particles of the body passes, regardless of the body's orientation. For simple geometric shapes made of uniform material, it coincides with the geometric center. ∑F⃗i=0sum of modified cap F with right arrow
If displaced, the body remains in its new position (the height of the center of gravity does not change). If displaced, the body remains in its new
An idealized model of a body where the distance between any two of its points remains constant, regardless of the forces applied.
