    Energy
In summary, the conversation discusses the idea of something being self-reliant for energy needs and whether such a thing is possible. It is mentioned that even the sun, which produces vast amounts of energy, relies on burning hydrogen and will eventually stop producing energy when the hydrogen runs out. The concept of perpetual motion is also brought up. The conversation also delves into the idea that an electron in a stationary state in an atomic orbital requires no energy, but this depends on the model used. It is also mentioned that a charged particle may require no energy to maintain a circular orbit in a magnetic field, but the magnetic field itself requires energy to create and sustain.

What is the word for something if it is self-reliant for energy needs to work?

Interesting question, but strictly speaking there is nothing that can be totally self reliant in energy needs cause that would essentially mean the creation of energy from nothing. Even the sun relies on "burning" hydrogen to produce the vast amount of energy it does, when the hydrogen in the sun will be depleted it ll stop producing energy.

Context matters, but it sounds a bit like you are referring to perpetual motion.

an electron in a stationary state in an atomic orbital requires zero energy and depending on what model you choose you could say it is moving in an "orbit", I use the term loosely.

not sure but I think it requires no energy for a charged particle to maintain a circular orbit in the classical sense in a magnetic field altho the magnetic field takes energy to create and sustain.

FAQ: Anything that does not depend for energy

What is the meaning of "Anything that does not depend for energy"?

This phrase refers to any objects, substances, or processes that do not require external sources of energy to function or exist. Examples include objects in outer space or particles that do not interact with other particles.

How does the concept of "Anything that does not depend for energy" relate to physics?

In physics, the concept of "Anything that does not depend for energy" is often studied in the context of conservation of energy. This principle states that energy cannot be created or destroyed, only transferred or transformed. Thus, objects or processes that do not depend on external sources of energy are of particular interest to physicists.

Can "Anything that does not depend for energy" exist in our world?

Yes, there are many examples of "Anything that does not depend for energy" in our world. For instance, stars in outer space produce energy through nuclear fusion and do not require external sources of energy to sustain themselves. Additionally, objects in a vacuum or particles with no interactions also fall under this category.

What are some potential applications of studying "Anything that does not depend for energy"?

Studying "Anything that does not depend for energy" can lead to a better understanding of fundamental principles in physics, such as conservation of energy. This knowledge can also have practical applications, such as in the development of renewable energy sources or in understanding the behavior of particles in extreme environments.

Are there any ongoing research or experiments related to "Anything that does not depend for energy"?

Yes, there are many ongoing research and experiments related to "Anything that does not depend for energy". For example, scientists are currently studying dark matter, which is a type of matter that does not interact with light and thus does not depend on energy for its existence. This research could potentially lead to a better understanding of the universe and its origins.
