Question

define centre of mass of a system
of particle force that the
velocity of centre of masa of
system ofparticle remain
constant if no external force
acting on it?"
​

Answer 1

The center of mass is a position defined relative to an object or system of objects. It is the average position of all the parts of the system, weighted according to their masses. For simple rigid objects with uniform density, the center of mass is located at the centroid.

Answer 2

Answer:

In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration.
