Centre of mass - definition of centre of mass by The Free Dictionary
網頁The center of mass of an object or set of objects is a place specified relative to it. It’s the average position of all the system’s components, weighted by their mass. The centroid is the location of the center of mass for basic rigid objects with homogeneous density. The object’s center of mass does not always fall in the same place. The experimental determination of a body's centre of mass makes use of gravity forces on the body and is based on the fact that the centre of mass is the same as the centre of gravity in the parallel gravity field near the earth's surface. The center of mass of a body with an axis of symmetry and constant density must lie on this axis. Thus, the center of mass of a circular cylinder of constant density has its center of mass on the a… farm animal suckers

網頁The center of mass is a position defined relative to system of objects. It is the average position of all the parts of the system, weighted according to their masses. In the case of a rigid body, the position of its center of mass is fixed in relation to the object. For instance, the center of mass of a uniform disc shape would be at its center. 網頁1 天前 · Even so, the protest will reportedly be held from 5:30 p.m. to 6:30 p.m. at Newton Centre Green on Thursday.
