1.3.1 - Uniform acceleration equations

Use the uniformly accelerated motion equations in one dimension: s = (u + v)t/2, v = u + at, s = ut + ½at², and v² = u² + 2as.

Use - uniform acceleration equations to connect the rule to the data and decision in the question.

This matters because - uniform acceleration equations determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - uniform acceleration equations to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: use the formula and units given in the question, show the substitution and interpret the result; the calculation alone is not the conclusion.
