Acceleration - a constant or increasing?

Click For Summary

Homework Help Overview

The discussion revolves around the behavior of an object accelerating in a vacuum when the force causing the acceleration is removed. Participants are exploring concepts related to Newton's laws of motion and the implications of no external forces acting on the object.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants reference Newton's first law and discuss the implications of removing the accelerating force, questioning whether the object's speed will remain constant or continue to increase. There is also a mention of quantum entanglement, which diverts from the main topic.

Discussion Status

The discussion is active, with participants providing insights into Newton's laws and engaging in clarifying questions. There is a mix of understanding and uncertainty regarding the implications of the laws in the context of the problem.

Contextual Notes

Some participants express a lack of recent familiarity with the material, indicating potential gaps in understanding. The original poster's scenario assumes a vacuum and the absence of friction, which is a critical aspect of the discussion.

Homework Statement


Object A is accelerating thru a vacuum; no forces (gravity, nada) acting on the object but the force accelerating it. The force accelerating the object is removed and no friction is involved.


Homework Equations


Will the object continue to accelerate at an ever-increasing speed or will speed remain constant once force is removed?


The Attempt at a Solution

What does Newton's first law state?
 
It's been a long time since I've been in school okay? I'm guessing law states: ... in motion stays in motion?
 
F=ma. No force = no acceleration. Velocity remains constant from then on.

Well yes but another way is that

A body at rest stays at rest, or if moving, continues to move in a straight line with uniform velocity provided that the resultant force on the body is zero.

So if you take away the accelerating force (or resultant force), then the ship should?
 
Yea, I knew that, just wish it wasn't true sometimes. F=ma, baby.

So, does quantum entanglement exceed the speed of light?

Hm. Not too sure. Best to ask in the Quantum Physics section, I am not too well versed in the details of entanglement.
 
Thanks for the help fella's.
