IGCSE Physics: Acceleration | Edexcel Modular | Unit 1 | L5

This lesson covers spec point 1.6 — knowing and using the relationship between acceleration, change in velocity and time taken.

PowerPoint includes:
• Retrieval starter reviewing speed calculations and distance–time graphs
• Direct Instruction (I Do) — acceleration defined as rate of change of velocity; a = (v − u) / t introduced in words and symbols; worked examples calculating acceleration, deceleration and time; negative acceleration explained as deceleration
• Guided Practice (We Do) — three calculations: find acceleration from a change in velocity; find time taken to reach a given speed; determine whether an object is accelerating or decelerating from data
• Independent Practice (You Do) — acceleration calculations from real-world contexts (cars, rockets, cyclists); rearrangement for u and t
• Review and Reflect — 3 MCQs and exit ticket calculation

Activity Sheet includes:
• Formula box: a = (v − u) / t
• 10 exam-style questions covering acceleration calculations, rearranging for u and t, and interpreting motion descriptions
• Stretch question requiring multi-step reasoning combining the acceleration and speed equations
• Full mark scheme for teacher use
