Discussion Overview

The discussion revolves around the concept of the acceleration of light, specifically questioning whether it has a defined value. Participants explore the implications of light's behavior in different contexts, including its initial velocity and acceleration in inertial frames.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions the possibility of defining an acceleration for light, referencing a formula for acceleration but noting that light has no initial velocity.
  • Another participant asserts that the acceleration of light is 0 in an inertial frame, suggesting this is a coordinate acceleration.
  • A subsequent reply reiterates the assertion of 0 acceleration for light in vacuum, emphasizing the context of inertial frames.

Areas of Agreement / Disagreement

There appears to be a consensus among participants regarding the acceleration of light being 0 in an inertial frame, though the initial question about defining acceleration remains somewhat unresolved.

Contextual Notes

The discussion does not clarify the assumptions underlying the definition of acceleration in this context, nor does it address potential variations in different media or frames of reference.

Is there a value for the acceleration of light? I tried to use a = v2-v02/2(x-x0) but then I just knew that light has no initial velocity so it can't be 0.

0 (coordinate acceleration in an inertial frame)
 
ah, I see
