GCSE AQA Physics - Force & Elasticity

New GCSE AQA Physics lesson on Forces and Elasticity written in line with new AQA Physics specification.

Lesson starts by discussing what elasticity is in relation to familiar, everyday objects which then challenge pupil thinking with ‘slo-mo’ videos of these objects being impacted.
Elasticity is then further explored with compression and tension in springs and also related to other objects.
To assist pupils in their understanding of the force extension graphs for materials proportionality is reviewed mathematically.

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.

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.
