Edexcel GCSE Physics Topic 8 REVISION (Energy-forces doing work)

This revision lesson has been filled with activities that will challenge the students on their knowledge and understanding of the content detailed in topic 8 (Energy - forces doing work) of the Pearson Edexcel GCSE Physics specification. The wide range of activities in the engaging PowerPoint and accompanying resources will check on the knowledge of this topic and allow the students to recognise those areas which need further attention before the mock or terminal GCSE exams.

This resource has been designed to cover as much of topic 8 as possible but the following points have received particular attention:

• Describe how to measure the work done by a force
• Understand that work done is equal to energy transferred
• Recall and use the equation to calculate work done
• Calculate the changes in energy involved when a system is changed by work done by forces
• Recall and use the equation to calculate gravitational potential energy
• Recall and use the equation to calculate kinetic energy
• Explain how energy is dissipated so that it is stored in less useful ways
• Define power as the rate at which energy is transferred and that 1 watt is equal to one joule per second
• Recall and use the equation to calculate power
• Recall and use the equation to calculate efficiency

The mathematical content of this specification and this topic is heavy and in line with this lots of calculated-based tasks are included and all of the answers are explained in steps so students can assess their progress

The main task of the lesson which challenges students to use the principle of moments has been differentiated so that differing abilities can access the work
