The torques that are produced by internal forces do not need to be considered because they always combine to produce a zero net torque. The farther a particle is from ...

... An isolated system is one for which there are no energy transfers across the boundary. The energy in such a system is conserved , i.e., at anytime the sum is a constant but its form can change in part or in whole. E.g., a block sliding across a frictionless table is moving in an isolated system. If ...
