A comprehensive lesson which teaches students about Hooke’s law, the spring constant equation, Stress strain graphs and how to calculate Young’s modulus based on this. Lesson is tailored towards the AQA A-level physics specification - Mechanics and Applied Science level 3 Edexcel Unit 5 Physics.
LO: To evaluate stress/strain graphs to determine Young’s modulus and apply this to situations.
By the end of the lesson learners should be able to:
Success criteria:
SC1: Recall Hooke’s law and identify limits of proportionality and plastic deformation on a graph.
SC2: Describe how to calculate Young’s Modulus from a tensile stress-strain curve.
SC3: Explain why rubber is effective at cushioning shocks.
For the a-level content: as a separate document included as pdf.
Contains past paper questions that target this topic, some questions require knowledge from prior lessons. There is also a guide attached with written walkthroughs of how to reach the final answer, even for those tricky 1 mark questions.
For btec unit 5 applied science: questions are on the slides following the lesson.
Powerpoint contains 27 slides and 12 past paper questions.
