Conservation Of Energy (Noun)
Meaning
The fundamental principle of physics that the total energy of an isolated system is constant despite internal changes.
Classification
Nouns denoting cognitive processes and contents.
Examples
- The conservation of energy states that the total energy of an isolated system is constant, meaning that energy cannot be created or destroyed, only converted from one form to another.
- According to the law of conservation of energy, a closed system will always retain the same amount of energy, even if the forms of energy within it change.
- The concept of conservation of energy has far-reaching implications for engineering design, as it allows engineers to optimize the efficiency of energy conversion systems.
- In physics, the conservation of energy is often expressed mathematically as ΔE = 0, where ΔE is the change in total energy of an isolated system over a given time period.
- Historically, the law of conservation of energy was developed in the mid-19th century through the work of several prominent physicists, including Julius Robert Mayer and James Joule.
