1. Energy stores and systems

Available for over a year

In this episode, James Stewart and Ellie Hurer explore all the changes involved in the way energy is stored when a system changes. Suitable for: AQA, Edexcel, OCR. For more information on energy stores and systems, check out the BBC Bitesize website: https://www.bbc.co.uk/bitesize/guides/z8hsrwx/revision/1 Key learning objectives discussed in this episode: - A system is an object or group of objects. - There are changes in the way energy is stored when a system changes. - Students should be able to describe all the changes involved in the way energy is stored when a system changes, for common situations. For example: - an object projected upwards. - a moving object hitting an obstacle. - an object accelerated by a constant force. - a vehicle slowing down. - bringing water to a boil in an electric kettle. Throughout this section on Energy students should be able to calculate the changes in energy involved when a system is changed by: - heating - work done by forces. - work done when a current flows. - use calculations to show on a common scale how the overall energy in a system is redistributed when the system is changed.
