Attaining Threshold Velocity V for Accelerating Object Mass M

Click For Summary

Discussion Overview

The discussion revolves around the concept of a threshold velocity V for an object with rest mass M, specifically in relation to the acceleration of its center of mass compared to a "Dimensional object." Participants explore the implications of this idea within the context of classical physics and potential scenarios involving extreme conditions, such as near a black hole.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants question the premise of defining a threshold velocity V and whether it is meaningful for an object with mass M in motion.
  • There is confusion regarding the term "Dimensional object" and its implications for defining speed and acceleration.
  • One participant suggests that under extreme acceleration, such as near a black hole, the center of mass could experience delays in its position change relative to the object, leading to complex interactions with gravitational fields.
  • Another participant challenges the notion of the center of mass accelerating faster than the object itself, seeking clarification on the underlying assumptions.

Areas of Agreement / Disagreement

Participants express differing interpretations of the initial question, with no consensus on the definitions or implications of the terms used. The discussion remains unresolved regarding the validity and clarity of the concepts presented.

Contextual Notes

Limitations include unclear definitions of "Dimensional object" and the relationship between the object's motion and its center of mass. The discussion also raises questions about the relevance of "rest mass" in the context of classical physics.

Can we define a threshold velocity V for an object with mass(rest) M which the object at motion need to attain so that its center of mass accelerates faster than the Dimensional object?

Why do you think the center of mass would accelerate faster than the object itself (assuming that's what you mean)?
 
I can't even make sense out of that question! Are you referring to a fluid "object" so that some parts are moving independently of the others? If so, what do you mean by the speed or acceleration of the "Dimensional object"? And why refer to "rest mass" when you posted this under "classical physics"?
 
1st: What's a dimensional object?
2nd: How do you define its speed if not by the speed of its center of mass as usual?

Since the position of the C.M of an object changes by virtue of the movement of its constituents, extremely high acceleration(alike to that experienced by an object in the vicinity of a black hole) could cause a delay in the change in position of the object relative to its C.M and the large object(black hole) would appear to have "polarised" the C.M to be contributing all of its mass to the center of mass of the large object(black hole). The object will then cease to exist as soon as it reaches the event horison whilst all its mass is now at the center of the black hole.
N.B: Just out of curiosity.
