Abstract: The Lagrange equation in center-of-mass frame of reference is derived. The constrain force can be obtained by using the Lagrange equation in center-of-mass frame of reference and the Lagrange equation in inertial reference frame, and an example is given to illustrate the application of the result.

Key words: center-of-mass frame of reference, Lagrange equation, constrain force
