The conservation of energy is a fundamental principle in physics that states that the total energy of an isolated system remains constant over time, meaning energy cannot be created or destroyed, only transformed from one form to another. This principle can be applied to various forms of energy, including kinetic, potential, thermal, electrical, chemical, and nuclear energy.
In a closed system, any energy lost by one part of the system must be gained by another, ensuring that the overall energy remains the same. This concept is crucial for understanding various physical phenomena and is a foundational concept in thermodynamics, mechanics, and many areas of science and engineering.
Mathematically, the conservation of energy can be expressed as:
\[ E_{\text{initial}} = E_{\text{final}} \]
Where \( E_{\text{initial}} \) is the total energy of the system at the beginning of an event or process and \( E_{\text{final}} \) is the total energy at the end of that event or process.
