Learning Objectives

6.1.1.1 Energy stores and systems

Content	Key opportunities for skills development
$A system is an object or group of objects. There are changes in the way energy is stored when a system changes. Students should be able to describe all the changes involved in the way energy is stored when a system changes, for common situations. For example: an object projected upwards a moving object hitting an obstacle an object accelerated by a constant force a vehicle slowing down bringing water to a boil in an electric kettle. Throughout this section on Energy students should be able to calculate the changes in energy involved when a system is changed by: heating work done by forces work done when a current flows$	$The link between work done (energy transfer) and current flow in a circuit is covered in Work done and energy transfer (page 146). WS 4.5$
$use calculations to show on a common scale how the overall energy in a system is redistributed when the system is changed.$	$WS 1.2, 4.3, 4.5, 4.6$
