IGCSE Physics: Scalars and Vectors | Edexcel Modular | Unit 1 | L2

This lesson covers spec points 1.13 and 1.14 — understanding how vector quantities differ from scalar quantities, and understanding that force is a vector quantity.

PowerPoint includes:
• Retrieval starter reviewing speed calculations from L1
• Direct Instruction (I Do) — scalar quantities defined (magnitude only); vector quantities defined (magnitude and direction); key examples of each introduced; force confirmed as a vector; speed vs velocity distinction made; distance vs displacement explained
• Guided Practice (We Do) — classify a list of quantities as scalar or vector; explain the difference between speed and velocity in context; identify how direction matters for forces
• Independent Practice (You Do) — exam-style classification questions; explain why the direction of a force matters; real-world vector contexts
• Review and Reflect and exit ticket classification task

Activity Sheet includes:
• 10 exam-style questions covering the scalar/vector distinction, examples, speed vs velocity, and distance vs displacement
• Table task: classify quantities and give units for each
• Stretch question requiring students to explain why two forces of equal magnitude can have different effects depending on direction
• Full mark scheme for teacher use
