Want this question answered?
That's called the center of mass.
The centre of mass.
No, many objects have no mass (at least no mass that is part of the body concerned) at their centre of mass. Not ,necessarily. Center of mass is an imaginary point.(at least no mass that is part of the body concerned)
Some objects have more mass, some have less.Some objects have more mass, some have less.Some objects have more mass, some have less.Some objects have more mass, some have less.
the mass of the objects and the distance of the objects
That's called the center of mass.
It is called the center of mass, this is the specific point where the mass seems to be concentrated.
center of mass
The centre of mass.
It is the nucleus. Mass of electrons is too small
It is a point where conceptually the entire mass of an object can be considered to be concentrated
There is no such thing. Do you mean definition? If so, it is the point at which the mass of an object can be considered to be effective/concentrated.
virtually all the mass in concentrated in the nucleus of the atom, as the electron's mass is so small, it is negligible.
The total mass of an object may be assumed to be concentrated at its centre of mass. It used to be called the centre of gravity.

A Lumped-Mass matrix, can be obtained by placing point (concentrated) masses, m_i, at node points i in the directions of the assumed displacement degrees of freedom.
