Conservation Of Energy - GCSE Physics Definition

The principle of Conservation of Energy states that energy cannot be created or destroyed; it can only be transferred from one form to another or moved from one place to another. In a closed system, the total amount of energy remains constant.

This means that while energy can change forms, such as from kinetic to potential energy or from chemical energy to thermal energy, the overall energy within the system does not increase or decrease.

For GCSE Physics students, this concept is crucial for understanding how energy is utilised in different processes, such as in engines, electrical circuits, and natural ecosystems.
