`        centre of mass?`

```										The center of mass or mass center is the mean location of all the mass in a system. In the case of a rigid body, the position of the center of mass is fixed in relation to the body. In the case of a loose distribution of masses in free space, such as shot from a shotgun or the planets of the solar system, the position of the center of mass is a point in space among them that may not correspond to the position of any individual  mass. The use of the mass center often allows the use of simplified equations of motion, and it is a convenient reference point for many other calculations in physics, such as angular momentum or the moment of inertia. In many applications, such as orbital mechanics, objects can be replaced by point masses located at their mass centers for the purposes of analysis.
The term center of mass is often used interchangeably with center of gravity,  but they are physically different concepts. They happen to coincide in a  uniform gravitational field, but where gravity is not uniform, center of gravity refers to the mean location of the gravitational force acting on a body. This results in small but measurable gravitational torque that must be accounted for in the operation of artificial satellites.
Barycenter or barycentre may also refer to the center of mass.
The center of mass of a body does not generally coincide with its  geometric center, and this property can be exploited. Engineers try to  design a sports car's center of mass as low as possible to make the car handle better. When high jumpers perform a "Fosbury Flop",  they bend their body in such a way that it is possible for the jumper  to clear the bar while his or her center of mass does not
The center of momentum frame is an inertial frame defined as the inertial frame in which the center of mass of a system is at rest. A specific center of momentum frame in which the center of mass is not only at rest, but also at the origin of the coordinate system, is sometimes called the center of mass frame, or center of mass coordinate system.

```										Centre of mass is basically an imaginary point. It has no existance.
It is the point where the whole mass of the body is supposed to be concentrated. As it makes the calculations easier by assuming the mass to be concentrated at just a one fixed point. Centre of mass of n bodies = (m1r1+m2r2+m3r3+......+mnrn)/(m1+m2+m3+......+mn)
