M1.3.1 - Constant-acceleration motion in a straight line

Motion in a straight line with Graphical solutions may be required, including constant acceleration. displacement-time, velocity-time, speed-time and acceleration-time graphs.; Knowledge and use of formulae for constant acceleration will be required.

Use constant-acceleration motion in a straight line to connect the rule to the data and decision in the question.

This matters because constant-acceleration motion in a straight line determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply constant-acceleration motion in a straight line to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Constant-acceleration motion in a straight line is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
