Particle Motion 2: Floating, Flying & Moving Freely in Space

Click For Summary

Discussion Overview

The discussion revolves around the concepts of floating, flying, and moving freely in space, exploring the definitions and implications of these terms in the context of physics and motion in a gravitational field. It includes theoretical considerations and interpretations of motion in space, particularly regarding gravity and orbital mechanics.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant defines floating in space as an experience of zero-gravity where objects appear massless due to the absence of gravitational pull from nearby massive objects.
  • Another participant describes flying as the process of movement through an atmosphere or space, involving lift, thrust, buoyancy, or ballistic motion, referencing a Wikipedia definition.
  • A different viewpoint emphasizes that mass is an intrinsic property of matter, unaffected by nearby masses, and that motion in space is relational and influenced by gravity, suggesting that true floating and flying do not occur in space.
  • One participant acknowledges a misunderstanding regarding the term "massless," clarifying it as "weightless."
  • A question is posed about the differences in satellite movement in the same orbital plane versus a higher plane, linking it to the dynamics of the Earth, Moon, and Sun.
  • Another participant notes that most objects in the solar system have orbital trajectories that are perpendicular to the rotational axis of the body they orbit.
  • A request for clarification is made regarding the previous question about satellite movement, indicating confusion over the original phrasing.

Areas of Agreement / Disagreement

Participants express differing views on the definitions and implications of floating and flying in space, with no consensus reached on these concepts. The discussion remains unresolved regarding the nature of motion in space and the specific question about satellite movement.

Contextual Notes

Some statements rely on specific interpretations of gravitational effects and orbital mechanics, which may not be universally agreed upon. The discussion includes assumptions about the nature of mass and motion that are not fully elaborated.

What is the meaning of floatin and flying and moveing freely in space?
 
Astronomy news on Phys.org
Floating in space is the experience of zero-gravity where the mass of any object that is far away from any planet or massive object tend to zero and it becomes relatively massless where no force pull him down or toward any center of any other massive. object
 
Well, flying is the act or process of flight.

Flight is the process by which an object moves either through an atmosphere (especially the air), or movement beyond (as in the case of spaceflight), by generating lift, propulsive thrust or aerostatically using buoyancy, or by simple ballistic movement.
(Per wikipedia on Flight)
 
Mass is an intrinsic property of matter and unaffected by the presence [or absence] of other nearby masses. Motion in space is difficult to quantify, it is strictly relational. Virtually all motion in space is influenced by gravity. Most things are either in a fixed orbit or follow a trajectory dictated by prior gravitational influence. Nothing much really 'floats' in space save perhaps near Lagrange points. Nothing 'flies' in space - there is no atmosphere. Just ablut everything moves freely in space - there is no resistance to speak of.
 
yes chronos you are right what I meant by massless is weightless sorry .
 
okey . what is the difference when a satellite moves in the same plane which planets takes from one planet to another and a higher plane . this question has no sense , you may think , but think a bout the moon and the Earth and the sun and the light .

It only makes no sense because i cannot understand you. Could you try asking that again?
