Question

Can someone explain Central Inertial Mass?

Answer 1

In physics, mass , more specifically inertial mass, can be defined as a quantitative measure of an object's resistance to the change of its speed.
this is what i know.

Answer 2

Doesn't it have something to do with it's momentum. In my text book it says " The center of inertial mass of a system of two interacting masses is defined to be that imaginary point such that, if all the mass of the system were concentrated there and moving with a velocity v , then the momentum of the center of inertial mass would equal the constant being the total momentum of the system.
