GCSE Physics P2 - Forces and Elasticity

Completely resourced lesson on Forces and Elasticity with key content from AQA and Edexcel Physics.

Learning Objectives:
- Identify objects in compression or tension.
- Explain what is meant by a proportional relationship.
- Describe an experiment to extension of an object due to force applied.
- Interpret and draw conclusions from a force-extension graph.

Lesson starts by discussing what elasticity is in relation to familiar, everyday objects which then challenge pupil thinking with 'slo-motion' videos of these objects being impacted.
Elasticity is then further explored with compression and tension.
A quick review on proportionality is covered through questioning supporting pupils in key maths skills required.

A class experiment is detailed using simple Physics equipment to test everyday materials for to produce a force-extension graph. Conclusions can then be drawn from the data produced in this experiment.
Hooke's law is detailed and related to a simply spring extension experiment and used to highlight spring constants.

Plenary poses a summary question for pupils to answer with detailed responses showing their understanding of elasticity.
