Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.
Clarification statement: Emphasis is on the quantitative conservation of momentum in interactions and the qualitative meaning of this principle.
Assessment boundary: Assessment is limited to systems of two macroscopic bodies moving in one dimension.
