It is especially useful because the real motion of object can be quite complicated. It might be a rotating and spinning as it travels, for example, a sommersaulting motocross bike getting some air-time across a wide gap. At the centre of mass, the bike and rider behave as a point ...
…gravity is identical to the centre of mass, a term preferred by physicists. The two do not always coincide, however. For example, the Moon’s centre of mass is very close to its geometric centre (it is not exact because the Moon is not a perfect uniform sphere), but its centre… ...

Noun1.centre of gravity- the point within something at which gravity can be considered to act; in uniform gravity it is equal to the center of mass center of gravity midpoint,centre,center- a point equidistant from the ends of a line or the extremities of a figure ...
Many people believe that the Centre of Mass Theorem is a powerful and useful tool in Newtonian Mechanics. In fact it is a farce. (1) It is trivially true...
We consider the simple and classical theorem of the motion of the centre of mass, pointing out that many textbooks append a wrong corollary to it: that the motion of the centre of mass is always independent from the internal forces. We give an explicit example showing that this corollary is...

Example 1 Centre Of Mass It is useful in certain calculations to consider animaginarypoint in a body of matter where, the total mass orweightof the body seems to concentrate at. The imaginary point is termed as the centre of mass.
Fig. 2. Example trace from one participant showing the vertical displacement of the centre of mass over the gait cycle. The vertical displacement values reported in the present study reflect the minimum to maximum peak value. Table 3. Vertical displacement of the CoM and between-group difference...
