Ask AI: What is the conservation of energy

The conservation of energy is a fundamental principle in physics, which states that the total energy in a closed system remains constant over time. In other words, energy cannot be created or destroyed, but can only be converted from one form to another. This principle is based on the first law of thermodynamics and is applicable to all physical processes, including mechanical, thermal, electrical, and chemical processes. This means that the sum of all forms of energy (such as kinetic, potential, thermal, etc.) in a closed system remains the same even though energy may change from one form to another. As a simple example, when a ball is dropped from a certain height, its potential energy gets converted into kinetic energy. However, the total energy in the system (potential + kinetic) remains the same throughout the process.
