Energy Conservation and Dissipation
What you need to know
Understand the principle that energy can be transferred usefully, stored, or dissipated, but it can never be created or destroyed.
Describe, using qualitative examples, where energy transfers occur in a system and understand that in a closed system, there is no net change to the total energy.
Explain how, in all system changes, some energy is dissipated and stored in less useful ways, often described as 'wasted' energy.
Calculate the quantitative energy changes associated with a system, recalling and selecting relevant equations for mechanical, electrical, and thermal processes.
Express the overall redistribution of energy in a system quantitatively on a common scale.
