Discussion Overview

The discussion revolves around the nature of motion, specifically whether it is classified as a scalar, vector, or neither. Participants explore definitions and implications of motion in various contexts, including its quantifiability and complexity.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions whether motion can be considered quantifiable, suggesting that while velocity, momentum, and kinetic energy can be measured, motion itself cannot be.
  • Another participant seeks clarification on the term "quantifiable," prompting a definition that relates to assigning numerical values.
  • A different perspective introduces a definition of motion as a time-dependent map from phase space to phase space, indicating a complexity that may transcend simple scalar or vector classifications.

Areas of Agreement / Disagreement

Participants express differing views on the quantifiability of motion and its classification, indicating that multiple competing perspectives remain without consensus.

Contextual Notes

Limitations include varying definitions of motion and the implications of quantifiability, which are not fully resolved in the discussion.

Is Motion a scalar or vector or neither?
 
Physics news on Phys.org
Motion is not something even quantifiable. You can say a system has a higher velocity, or more momentum or more kinetic energy, but not more motion.
 
excuse me, what do you mean by quantifiable?
 
One definition of motion I have seen is a time-dependent map from phase space to phase space. Which is quite a bit more complex than scalar vs vector.
 
'quantifiable' = capable of having a number, or quantity, assigned to it.
