Does Centre of mass and Centre of gravity is same of different ?
Centre of mass of a body is a point where whole mass of the body may be supposed to be concentrated for describing its translatory motion .
On the other hand centre of gravity is a point at which the resultant of the gravitational forces on all the particles acts. Or in other words where whole mass of the body may be supposed to act.
On the surface of earth and for the normal dimensions, centre of mass and centre of gravity coinsides. But these two relates to different concepts. For example centre of mass and centre of gravity may be different at greater heights. At mount everest centre of gravity lies below the centre of mass.
Lets reflect on this discussion.
Centre of gravity may change its direction in order to keep the system balanced.
