Physics · Centre of mass of a two-particle system, centre of mass of a rigid body
The motion of centre of mass depends on
The motion of centre of mass depends on
- A. total external forces
- B. total internal forces
- C. sum of \( (a) \) and \( (b) \)
- D. None of these
Step-by-step solution
The motion of the centre of mass is governed by Newton's second law applied to the system as a whole: the net external force equals the total mass times the acceleration of the centre of mass. Internal forces cancel in pairs and do not affect the centre of mass motion.
