M2.4.1 - Momentum as a vector

Momentum as a vector.; The impulse-momentum principle in vector form.; Conservation of linear momentum.

Use momentum as a vector to connect the rule to the data and decision in the question.

This matters because momentum as a vector determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply momentum as a vector to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Momentum as a vector is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
