GCSE Physics · key term
The principle that energy cannot be created or destroyed; it can only be transferred between stores.
Used by AQA, Edexcel and OCR
Specification 4.1.1.1, 4.1.2.1 · Paper 1
The principle that energy cannot be created or destroyed; the total energy of a closed system remains constant.
Revise: Energy stores and systemsDissipation does not break conservation of energy.
Specification 3.4, 3.6, 3.8, 8.1, 8.3 · Paper 1, Paper 2
The rule that energy cannot be created or destroyed; it can only be transferred between energy stores, so the total amount remains constant.
Revise: Conservation of EnergyEnergy cannot be created or destroyed; it can only be transferred between stores. This is the principle of conservation of energy.
Specification P7.1a, P7.2a · Paper 2 (Foundation), Paper 4 (Higher)
The principle that energy cannot be created or destroyed; transfers do not change the total energy of a closed system.
Revise: Conservation of energyThe law of conservation of energy says that energy cannot be created or destroyed. A closed system has no energy entering or leaving it. Energy may move between stores within that system, but its total energy is the same before and after the transfers.
The rule that energy cannot be created or destroyed; in a closed system, its total amount remains constant.
Paper 1, Paper 2
The principle that energy cannot be created or destroyed; the total energy of a closed system remains constant.
Revise: Energy Conservation, Dissipation and InsulationDissipation does not break the conservation of energy.
The principle that energy cannot be created or destroyed, so total energy input equals total energy output.
State the system boundary before applying conservation of energy. Energy apparently ‘lost’ from one object may have entered the thermal stores of its surroundings.
