This resource contains a full lesson (presentation) on the topic ‘Changes in Energy Stores’ in the AQA physics GSCE syllabus. The presentation contains the following learning criteria outlined in the syllabus: Know the definition of a system. Describe all the changes involved in the way energy is stored when a system changes. Common situations include: an object projected upwards a moving object hitting an obstacle an object accelerated by a constant force a vehicle slowing down an electric kettle boiling water Calculate how energy is redistributed in a system when it changes. Along with the presentation is a worksheet to show progress made against the learning criteria.

Revision material for energy calculations. Includes all the equations (with equation triangles) stated in the AQA specification. Work done Kinetic Energy Gravitational Potential Energy Elastic Potential Energy Specific Heat Capacity Power Efficiency Also contains exam questions with answers.
