The angular momentum principle may be extended to a multiparticle system to provide various insights.
The Main Idea
A Mathematical Model
The derivation of the angular momentum principle of a multiparticle system is most easily understood when following a simple example, in this case we will work with a three particle system:
- The angular momentum principle is written for each individual particle relative to location A, with position vectors r and external force vectors F.
- The individual equation is then summed. Note that, due to the reciprocation of forces, the internal forces f cancel out.
- The equation is now rewritten with the right side, representing net torque, as τnet,A
