Discussion Overview

This thread explores various fundamental concepts in physics, including the nature of matter and energy, the behavior of electromagnetic waves, the definition of heat, and the interactions between charged particles. Participants pose questions and provide responses that touch on theoretical and conceptual aspects of physics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • Some participants assert that matter is not simply "frozen" energy, suggesting that while matter has energy, it is not accurate to define it as energy itself.
  • There is a discussion about heat being the transfer of thermal energy rather than the energy itself possessed by a hot body.
  • Participants debate the nature of electromagnetic waves, with some suggesting they interact with atoms through disturbances in electric and magnetic fields.
  • Questions arise about the propagation of light in space, with some arguing that fields exist even in outer space, while others challenge this notion.
  • Some participants express confusion regarding the definition of light as propagating fields, questioning the meaning of "propagate" in this context.
  • There are inquiries into the processes of matter-energy conversion, with references to Higgs particles and their role in mass generation.
  • Participants discuss the emission of energy by accelerated charged particles, with some clarifying that energy is required for acceleration.
  • There is a contention regarding the definition of electric charge and the mechanisms by which electrons attract protons, with references to virtual particles and force mediation.

Areas of Agreement / Disagreement

The discussion contains multiple competing views and remains unresolved on several points, particularly regarding the definitions and interactions of fundamental concepts such as energy, heat, and electromagnetic waves.

Contextual Notes

Participants express varying levels of understanding and terminology, leading to potential confusion over concepts like thermal energy versus heat, and the nature of light and electromagnetic fields. Some responses indicate a reliance on specific definitions that may not be universally accepted.

Who May Find This Useful

This discussion may be of interest to individuals exploring foundational physics concepts, particularly those related to energy, matter, and electromagnetic theory.

please read all the question and when answering only some, mention which question you are answering
1. matter is a "frozen" energy (yes or no)
2. heat is energy, measured by the movement speed of molecules
3. electromagnetic waves as the go next to the to the atomes they pull and push the atomes (or molecules) because of the binary change - disturbence in the electricity field and disturbance with the magntic field
4. the disturbance in the fields is the fields of the atomes create
5. who can a ray of light go through outer atmosphere space, there are no fields there!
6. you may say a ray of light is not going but propagating, but it is not stretching but a disturb that moves forword (for example, 1 meter light wave moves as one meter light wave from sun to earth). [was the particle phase of energy an instrumental theory?]
7.why every object that accelerate (faster or slower) is emits energy?
8.one atom is a neutral magnetic unit. if we take 2 magnets and get the + of one of them to touch the - of the other, why (and maybe there it is & i don't know) there is no canceling affect like in atom which become neutral?

thank you very much!

No. Matter has energy, like it has mass, or charge, or velocity. I wouldn't say that it is energy.

Heat is the transfer of energy from a hot body to a cold body in thermal contact.

I don't understand your questions here, can you re-phrase them?
meni ohana said:

Yes, there are fields in space.
meni ohana said:

On the contrary, it takes energy for an object to accelerate.

Not all atoms are magnetically "neutral", many have a magnetic dipole moment. This is a key fact used in nuclear magnetic resonance.
 
thank for answering me!

A is electron can be defined as one side magnet?

B what is electric charge means? I've been taught that every power is a particle. so when elctron attract proton how does he do it? (what does it sends to attract?)

C if a body is hot then it has already possesses heat!

D why the definition of light is propagating fields of magnet and electricty? the meaning of propagate is to multyply, to be more than it was before or spread. but light dosn't act like that! it goes straight from the source in a linear way (affected of course by the gravity)!
although i still don't know the answer of B yet, i know that there are no magntic and electric fields everywhere in outer space, therfore, light can travel regardless there are fields or not.

E can you tell me what is the process of turning matter can turn into energy and energy can become matter? are higgs particles join\create when the energy exceeds certain level? and when positron and electron meets they loose all the higgs?

F not very important, i was trying to explain to my self why heat is not good for me. heat is not good for me because it ruins my protein and other organic compounds. and how heat is doing it? the atomes that are not me makes my atomes go faster. and how the atomes that are not me go fast? the ray of light which comes from the sun is crossing next to an atom by doing so, the "propagating" magnetic field of the light makes the electrones in the atomes to move, the negative charge of the electron (which has just moved) pushes the positive proton and the whole atom moves becuse of that...at least in my mind, with mechanical explanation

G I've made a mistake, charged particle does emits energy when crossing a magnetic field and accelerate

thank again!

Accelerated charged particles emit energy.

No, an electron is definitely not a monopole.

Charge is just a property possessed by certain particles which gives rise to and interacts with the electromagnetic force. I assume that by "every power is a particle", you are referring to force-mediating bosons. The electromagnetic force is mediated by photons. The exchange of photons between the two interacting bodies give rise to the force.
meni ohana said:

It possesses thermal energy, not heat! Heat, as Dale pointed out earlier, specifically refers to the transfer of thermal energy from one body to another.

I don't understand the point you are trying to make here, but light, or electromagnetic radiation is composed of mutually perpendicular time-varying (ie oscillating) magnetic and electric fields. That is what light is.

Fusion and fission are some notable examples of mass-energy being converted into other forms of energy. It seems like you have some strange perception of the Higgs boson. Coupling with the Higgs field is proposed to be the origin of mass. If we want to be able to detect the Higgs boson, then we must have collisions in which the energy exceeds the rest mass(-energy) of the Higgs boson.

No, there is no such thing as a magnetic monopole.

They are called "http://en.wikipedia.org/wiki/Virtual_particle" ", but you probably should learn classical mechanics and EM first.

meni ohana said:

The term you are thinking of is "thermal energy". If a body is hot then it has a lot of thermal energy. Heat is the transfer of that thermal energy from one object to another.

The correct terminology is not usually terribly important in this case. Many people, including myself, often use "heat" as a synonym for "thermal energy". It is technically incorrect, but people will understand what you say.

I don't know why you think that there are no magnetic and electric fields in outer space. The http://en.wikipedia.org/wiki/Cosmic_microwave_background_radiation" is throughout all of space and has its own EM fields.

Again, I would recommend that you learn classical mechanics and EM first. As far as turning matter into energy and vice versa you can look at http://en.wikipedia.org/wiki/Pair_production" .

Sounds good to me. You can also think of it in terms of conservation of energy. The EM fields contain energy, which is transferred to the material when the field is absorbed.
