What is the define centre of mass of a body?

The center of mass of a body is the point at which its mass is evenly distributed in all directions, essentially acting as the average location of the mass of the object. It is the point that moves as if all the body's mass were concentrated at that point when subjected to external forces. In a uniform gravitational field, the center of mass coincides with the center of gravity, making it crucial for analyzing motion and stability in physics. The position of the center of mass depends on the shape, mass distribution, and dimensions of the body.
