1.3.9 - Newton’s second law and terminal velocity

Be able to use the equation ∑F = ma, and understand how to use this equation in situations where m is constant (Newton’s second law of motion), including Newton’s first law of motion where a = 0, objects at rest or travelling at constant velocity Use of the term ‘terminal velocity’ is expected.

Use - newton’s second law and terminal velocity to connect the rule to the data and decision in the question.

This matters because - newton’s second law and terminal velocity determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - newton’s second law and terminal velocity to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Newton’s second law and terminal velocity is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
