The law of conservation of energy states that energy cannot be created or destroyed. (True/False)

The statement "The law of conservation of energy states that energy cannot be created or destroyed" is True.

The law of conservation of energy is a fundamental principle in physics, stating that the total energy of an isolated system remains constant over time. Energy can only be transformed from one form to another (e.g., potential to kinetic, chemical to thermal) or transferred between objects, but it is neither created nor destroyed in the process.

For example:

• When a ball falls from a height, its potential energy decreases, but the lost energy is converted into kinetic energy and later into heat and sound upon impact.
• In chemical reactions, energy may change forms (e.g., exothermic reactions release heat, while endothermic reactions absorb it), but the total energy before and after remains the same.

This principle is widely applied in thermodynamics, mechanics, and engineering to analyze energy systems efficiently.
