Curriculum content descriptions

Energy conservation in a system can be explained by describing energy transfers and transformations (ACSSU190)

Elaborations
• recognising that the Law of Conservation of Energy explains that total energy is maintained in energy transfer and transformation
• recognising that in energy transfer and transformation, a variety of processes can occur, so that the usable energy is reduced and the system is not 100% efficient
• comparing energy changes in interactions such as car crashes, pendulums, lifting and dropping
• using models to describe how energy is transferred and transformed within systems
