Forces and matter REVISION (Topic 15 Edexcel GCSE Physics)

This revision lesson is fully-resourced and has been written to allow students to assess their understanding of the content detailed in topic 15 (Forces and matter) of the Pearson Edexcel GCSE Physics specification. The engaging and detailed PowerPoint uses a wide range of activities, which includes exam-style questions with clear explanations of the answers, to enable the students to identify those areas which require further attention before the mock or terminal examinations.

The lesson was designed to cover as much of the topic as possible but the following points have received particular attention:

• The difference between elastic and inelastic distortion
• Recall and use the equation for linear elastic distortion
• Use the equation to calculate the work done in stretching
• Describe the relationship between force and extension
• Recall and use the equation for pressure
• Describe how pressure in fluids increases with depth and density
• Use the equation to calculate the magnitude of pressure in liquids
• Explain that an object in a fluid is subjected to upthrust
• Calculate the depth at which an object floats

Due to the heavy mathematical content of this specification and particularly this topic, a lot of the activities challenge the students on their ability to recall and apply the equations. Step-by-step guides and differentiated resources are used to allow students of differing abilities to access the work.
