Energy appears in different forms, including movement (kinetic energy), heat and potential energy, and energy transformations and transfers cause change within systems (ACSSU155)

Elaborations
  • 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
