The non-relativistic behavior of particles

Click For Summary

Homework Help Overview

The discussion revolves around the non-relativistic behavior of particles as described by the Schrödinger equation. Participants are exploring the definitions of momentum and energy in non-relativistic contexts compared to relativistic contexts.

Discussion Character

  • Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • The original poster seeks an explanation of non-relativistic behavior. Some participants provide definitions of momentum and energy, while others question the implications of these definitions when velocities are much smaller than the speed of light.

Discussion Status

Participants are actively engaging with the concepts, with some providing clarifications and corrections to earlier statements. There is an ongoing exploration of the relationship between non-relativistic and relativistic equations, but no consensus has been reached.

Contextual Notes

There is a mention of potential confusion regarding the energy equation and its components, indicating a need for clarity on the definitions used in both non-relativistic and relativistic frameworks.

hello
When I was studing about the Schrödinger equation,I read that it describes the non-relativistic behavior of particles .
But I don't know what is the non-relativistic behavior of particles . S o I need somebody to explain this behavior .

Hi FRANCLI! :smile:

It means that we can define momentum = mv and energy = 1/2 mv2.

(relativistic behavior of particles is more accurate, and defines momentum = mv/√(1 - v2/c2) and energy = m/√(1 - v2/c2), which are approximately the same as the non-relativistic definitions when v is very much smaller than c :wink:)

thank you ,
but if the energy is = 1/√(1 - v2/c2), and v is very much smaller than c , the energy will be 1 ?
 
oops!

oops! :redface: … i missed out the "m" :rolleyes:

it should have been energy = m/√(1 - v2/c2)

(or KE = m/√(1 - v2/c2) - m, which is approximately 1/2 mv2 when v is very small)

(i've edited my last post, so it's correct now :wink:)
 
OK, thanks .
