Discussion Overview

The discussion explores the effects on atomic behavior when an object is struck, specifically focusing on atomic vibrations, energy transfer, and the potential for electrons to be freed from materials. The scope includes conceptual and experimental considerations.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant asks if hitting an object causes its atoms to vibrate more, suggesting that sound waves and energy transfer occur.
  • Another participant confirms that hitting the table produces sound waves and causes vibrations among many atoms, rather than individual atoms.
  • A later post questions whether the energy from hitting an object can cause electrons to reach the vacuum level and leave the material.
  • Some participants express skepticism about the feasibility of freeing many electrons in realistic scenarios, though they acknowledge that some electrons might escape.
  • There is a proposal about the possibility of creating a device to detect stray electrons that leave the object when struck, with a follow-up suggestion that heating the object might be a more effective method for producing free electrons.

Areas of Agreement / Disagreement

Participants generally agree that hitting an object causes atomic vibrations and can produce sound waves, but there is disagreement regarding the extent to which electrons can be freed from the material and the practicality of detecting them.

Contextual Notes

Participants do not fully resolve the conditions under which electrons might be freed or the effectiveness of different methods for producing free electrons.

What happens to the atoms if an object is hit? If I hit my table, will it cause atoms to vibrate more?

Short answer: Yes

Your hit will produce sound waves, traveling trough the table. Some fraction will go to other objects (or the air), another fraction will be absorbed by the table (heating it a bit).
Note that those are vibrations of many atoms relative to many other atoms, not a vibration of individual atoms.
 
Great. thanks for your help. now, if i go a step further and ask if this energy transferred to the object is able to make electrons reach the vacuum level (have the electrons completely leave the material)? what do you think, is that possible?
 
I don't think you free many electrons with realistic setups. But some of them might leave the metal.
 
Do you think it is possible to create a device that is able to realize these stray electrons?
In other words can you create an electron detector that would detect such electrons (the ones that leave the object) at a distance, or is this far fetched? This was my initial question, but I had to ask the previous two questions to set the question up right!
 
In a vacuum? Probably.
Where is the point? You can just heat the object, this is a better method to produce free electrons.
 
hmmm. well said
