Energy appears in different forms, including movement (kinetic energy), heat and potential energy, and energy transformations and transfers cause change within systems (ACSSU155)
recognising that kinetic energy is the energy possessed by moving bodies
recognising that potential energy is stored energy, such as gravitational, chemical and elastic energy
investigating different forms of energy in terms of the effects they cause, such as gravitational potential causing objects to fall and heat energy transferred between materials that have a different temperature
recognising that heat energy is often produced as a by-product of energy transfer, such as brakes on a car and light globes
using flow diagrams to illustrate changes between different forms of energy
