What does the law of conservation of energy state?

The law of conservation of energy states that energy cannot be created or destroyed; it can only be transformed from one form to another. This principle is fundamental in physics and implies that the total energy in an isolated system remains constant, although it may change forms—such as from kinetic energy to potential energy or from thermal energy to mechanical energy.

This understanding is essential in various applications, including mechanics, thermodynamics, and even biochemical processes. By recognizing that energy can change forms but the total amount remains unchanged, students can better grasp concepts in both science and engineering, as well as the natural phenomena occurring in everyday life. This principle underscores the interconnectivity of different energy types and how they interact within systems.
