As we know that for a system of n particles, we can relate position vector of centre of mass and that of individual masses as * Internal forces are action-reaction pairs and hence, cancels out and only vector sum of external forces remains.

We can also define centre of mass in terms of vector. let rᵢ be the position vector of the ith particle and R be the position vector of the centre of mass, then Centre Of Mass Of Rigid Continuous Bodies For a real body which is a continuous distribution of matter, point masses are then

A point at which the entire mass of the body or system of bodies is supposed to be concentrated is known as the centre of mass. Centre Of Mass For A System Of Two Particles Let the distances of the two particles be x₁ and x₂ respectively from origin O. Let m₁ and m₂ be
A body is said to be a Rigid Body when it has a perfectly definite shape and size. The distance between all pairs of particles of such a body do not change while applying any force on it. Example:- A wheel can be considered as Rigid Body by ignoring a little change in its shape.
