I was reading on the conservation of momentum and they mention how in isolated systems momentum is always conserved and if the external forces of the system is zero. In the case of friction or drag acting against the motion of a body would that be considered as part of the isolated system or an external force not equalling to zero? Would momentum for the body be conserved? for example a boat at constant velocity is subjected to a drag force due to water resistance
