M2.4.2 - Direct impact of elastic particles

Use Newton’s law of restitution for direct impact of elastic particles, with 0 ≤ e ≤ 1, and determine loss of mechanical energy.

Use direct impact of elastic particles to connect the rule to the data and decision in the question.

This matters because direct impact of elastic particles determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply direct impact of elastic particles to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Direct impact of elastic particles is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
