Acceleration in an inertial reference frame

Click For Summary

Homework Help Overview

The discussion revolves around the concepts of acceleration and velocity in inertial reference frames, specifically questioning whether these quantities remain consistent across different inertial frames.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to understand the implications of acceleration and velocity being zero in one inertial frame and questions if this holds true in all inertial frames. Participants inquire about the definitions and properties of inertial reference frames.

Discussion Status

The discussion is ongoing, with participants exploring definitions and properties of inertial reference frames. Some guidance has been offered regarding the nature of reference frames, but no consensus has been reached on the original poster's questions.

Contextual Notes

Participants are examining the definitions and implications of inertial reference frames, which may involve assumptions about the nature of motion and reference systems.

Homework Statement


3. (a) If an object's acceleration is zero in one inertial reference frame then is its acceleration zero in all other inertial reference frames? (b) If an object's velocity is zero in one inertial reference frame then is its velocity zero in all other inertial reference frames?

Homework Equations

The Attempt at a Solution


I think it's going to be zero in both questions both I'm not so sure and I need an explanation

Hi Swag ranger,

Welcome to Physics Forums.

What do you know about inertial reference frames? How are they defined?

No, not quite. A reference frame is not necessarily associated with a particular object. It's a coordinate system that has particular properties (particularly with respect to other inertial reference frames).

Suggestion: Take a look at the Wikipedia article regarding Inertial Reference Frames:
