Center of mass - Comparison with center of gravity

The center of mass of an object is a point at which the object's mass can be assumed, for many purposes, to be concentrated. Center of mass - Example. For example, an object can balance on a point only if its center of mass is directly above the point. Alternatively, if you hang an object from a string, the object's center of mass will be directly below the string.

When talking about celestial bodies, the center of mass has a special relevance: when a moon orbits around planet, or a planet orbits around a star, both of them are actually orbiting around their center of mass, called the barycenter, see two-body problem. The barycenter (from the Greek βαρύκεντρον) is the center of mass of two or more bodies which are orbiting each other, and is the point around which both of them orbit. It is an important concept in the fie ...

The following equations of motion assume that there is a system of particles governed by internal and external forces. An internal force is a force caused by the interaction of the particles within the system. An external force is a force that originates from outside the system, and acts on one or more particles within the system. The external force need not be due to a uniform field. For any system with no external forces, the center of mass moves with constant velocity. This applies for all systems with classical internal forces, in ...

The center of mass is an important point on an aircraft, as it defines the amount of mass forward or behind the center of gravity that needs to be moved in order to pitch the plane up or down without applying any external forces. In conventional designs the center of mass is often located very near the line 1/3rd back from the front of the wing. That is the line where most wings generate their lift, known as the center of pressure, so by balancing the plane at that point, the lift and weight balance out with no net torque. The center ...

In the discrete case: where n is the number of mass particles. Or in the continuous case: where ρ(s) is the scalar mass density as a function of the position vector. If an object has uniform density then the center of mass is the same thing as the centroid. ...

The center of mass is defined as the weighted average of position, with in the discrete case the masses as weights, and in the continuous case the density function as the weight function. Thus the center of mass of an object is the position vector given by: . ...
