IGCSE Physics: Velocity-Time Graphs | Edexcel Modular | Unit 1 | L6

This lesson covers spec points 1.7, 1.8 and 1.9 — plotting and explaining velocity–time graphs, determining acceleration from the gradient, and calculating distance from the area under the graph.

PowerPoint includes:
• Retrieval starter reviewing acceleration calculations and DT graph interpretation
• Direct Instruction (I Do) — VT graph features explained with annotated examples; gradient = acceleration; area under graph = distance travelled; positive gradient, negative gradient and horizontal line identified and explained; area calculations for triangles, rectangles and trapeziums
• Guided Practice (We Do) — calculate acceleration from a VT graph gradient; calculate distance for a constant-velocity section; calculate total distance for a multi-section journey
• Independent Practice (You Do) — multi-section VT graph analysis; gradient and area calculations; sketch a VT graph from a written description of motion
• Misconception check: VT graph vs DT graph — common student confusion addressed
• Review and Reflect — Exit ticket graph analysis

Activity Sheet includes:
• Formula box: a = Δv / t; distance = area under graph
• Annotated multi-section VT graph for reference
• 10 exam-style questions covering gradient, area (triangle, rectangle, trapezium), graph description and sketching
• Stretch question requiring full analysis of a complex multi-section VT graph including acceleration, deceleration and total distance
• Full mark scheme for teacher use
