WebFACT: The center of mass of a system of objects obeys Newton’s second law- F = Ma cm. Usually the location of the center of mass (cm) is obvious, but for several objects is expressed as: Mx cm = m 1 x 1 + m 2 x 2 + m 3 x 3, where M is the sum of the masses in the expression. In some cases the center of mass is not located on the body of the ... Web4 Meeting House Rd Ste 6-8, Chelmsford, MA 01824 (978) 454-9811.
