Forces and Elasticity 4 Force-extension graphs

GCSE Combined Science and Physics (9 - 1) Forces and Elasticity: Analysing the Force-extension graphs for the extension of a spring required practical. This is lesson 4 of 4 for this section of the GCSE specifications with 3 PowerPoint presentations and 2 supporting student worksheets.

The lesson includes:

Starter activity: Multiple choice questions to check understanding of the terms independent variable, dependent variable and control variable for this investigation.

Discussion of the Force against extension graphs for the extension of a spring investigation including key terms, calculating gradient and area under the graph.
Discussion and calculations of Elastic Potential Energy for the spring.
Practical instructions to calculate the elastic potential energy of an extended spring.
Plenary question to check students understanding of the use of formulae with a F-e graph.

Additional PowerPoint presentations

To support students in rearranging the formulae in this topic a presentation using formula triangles is included. These slides can be used as they are or fitted into the most appropriate part of the lesson(s) for the topic.

A summary PowerPoint presentation includes an outline all the information students need to know for this part of the topic. This can be used for revision or printed out as a student handout.
