What the formula does is gives an 'weighted average' of the average position of all the bodies in the sense that the bodies of greater mass contribute more strongly to the average. 1449 Views So the phrase 'centre of mass' simply means 'this formula'. In uniform objects (symmetrical) it is the geometric centre. The experimental determination of the center of mass of a body uses gravity forces on the body and relies on the fact that in the parallel gravity field near the surface of the earth the center of mass is the same as the center of gravity. Key Takeaways Key Points. It is the point at which it is balanced in all directions. The centre of mass of a body is where the mass is considered to be concentrated. Booster Classes.
