Locate the center of mass.

Assertion: If there are no external forces, the center of mass of a double star moves like a free particle. Reason: If we go to the center of mass frame, then we find that the two stars are moving in a circle about the center of mass, which is at rest.

Find the Xcm of center of mass of a barbell consisting of 50kg and 80kg weights at the opposite ends of a 1.5-along bar of negligible mass. [Hint] Choosing the origin at one the masses here conveniently makes one of the terms in the sum Sigmam_(i)x_(i)zero . But, as always, the choice of origin is purely for convenience and doesn't influence that actual physical location of the center of mass.

Define the center of mass of a body.

The sum of moments of masses of all the particles in a system about the center of mass is
