CENTER OF MASS
BASIC CONSEPT OF CENTER OF MASS
center of mass is a consept to simplify the problems
it condunces the system of masses in a synle particle of the mass equal to the total mass of the system

ACC OF COM
PROBLEMS ON THE SHIFTING OF PARTICLE AND COM
PROBLEMS ON CHANGING THE VELOCITY , ACC AND THE COM
it is evaluated in x,y,z corrdinates all of them
just like the kinamitics can be anylized in x,y,z the motion of com can be anylized in suh way also
