SUMMARY
The center of mass (COM) for two masses is calculated using the equation COM = (m1*x1 + m2*x2) / (m1 + m2), where m1 and m2 are the masses and x1 and x2 are their respective positions. For three masses, the equation extends to COM = (m1*x1 + m2*x2 + m3*x3) / (m1 + m2 + m3). This method applies the principle of mass distribution along a linear axis, allowing for accurate determination of the center of mass in both cases.
