SP1c Acceleration | Edexcel GCSE Physics Topic Mastery Pack

A complete revision and exam practice pack for SP1c Acceleration, covering the full Pearson Edexcel GCSE Physics (9–1) Separate Science specification for this topic. Higher tier content (v² − u² = 2ax) is included.

This pack contains three components:

Topic Mastery Sheet (PDF) - a comprehensive reference covering the definition of acceleration as the rate of change of velocity (not speed - and the sheet explains why the distinction matters), the equation a = (v − u)/t with a formula triangle, and the Higher equation v² − u² = 2ax. Both equations are developed through worked examples showing the correct layout of working that earns full marks: identify equation, rearrange if needed, substitute with units, evaluate, state answer with unit. Deceleration is treated as negative acceleration with a worked example showing how negative values emerge naturally from the equation. A reference table of typical accelerations (sprinter ~3 m/s², sports car ~10 m/s², free fall 10 m/s²) helps students evaluate whether their calculated answers are physically plausible. The common error of using speed instead of velocity in the equation is addressed directly in the Common Mistakes section.

Student Exam Practice Sheet (PDF + DOCX) - five exam-style questions: a multiple choice question on the unit for acceleration, a motorbike acceleration calculation (8 m/s to 24 m/s in 4 seconds), a car decelerating to rest question (finding deceleration and time), a Higher question using v² − u² = 2ax for a car accelerating over 45 m, and a question explaining why free-fall acceleration is the same for all objects regardless of mass.

Teacher Answer Key (PDF + DOCX) - full mark scheme with fully worked calculations for all numerical questions. The deceleration question answer includes the negative sign with a note that it indicates the direction of the force opposing motion. The Higher question answer shows both the substitution and the square root step.
