Facets:
Source sentences:
text: From the lesson we learned that the total linear momentum of a system of objects must be conserved (that is, unchanged) if no external forces act on that system.
text: Like velocity, linear momentum is a vector quantity, possessing a direction as well as a magnitude: Linear momentum is also a conserved quantity, meaning that if a closed system is not affected by external forces, its total linear momentum cannot change.
text: Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.
