What does your textbook say about the same origin. The symbol ∑?
(the Greek letter sigma) denotes summation, in this case over n particles. The sum is the total mass of the system. Suppose that we have three particles, not lying in a straight line. We may define x– and y – axes in the plane in which the particles lie and represent the positions of the three particles by coordinates ( x , y ), ( x , y ) and ( x , y ) respectively. Let the masses of the three particles be m , m and m respectively. The centre of mass C of the system of the three particles is defined and located by the coordinates ( X, Y) given by
