Inertial Frames of Reference: Examining Forces & Acceleration

Click For Summary

Homework Help Overview

The discussion revolves around the concept of inertial frames of reference in physics, particularly focusing on the nature of forces and acceleration within these frames. The original poster expresses doubts regarding the existence of inertial frames, the implications of zero acceleration, and the relationship between force and the state of rest of a particle.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to clarify the definition and implications of inertial frames, questioning whether they are purely theoretical. They also explore the relationship between acceleration and force, posing multiple-choice questions regarding the conditions under which a particle may be at rest.

Discussion Status

Participants are engaging in a conceptual exploration of the topic, with some questioning the original poster's assumptions and others expressing uncertainty about the answers. There is no explicit consensus on the correct interpretations of the questions posed.

Contextual Notes

The original poster's inquiries suggest a focus on conceptual understanding rather than problem-solving, indicating a desire to explore the foundational principles of mechanics related to inertial frames.

so here r ma doubts
=> it is sometimes heard tat inertial frame of referance is only an ideal concept and no such inertial frame exists.comment.

=>the accelaration of a particle is zero as measured from an inertial frame of referance . can we conclude tat no force acts on it?

=> a particle stays at rest as seen in a frame. we can conclude tat
1) the frame is inertal
2) resultant force on the particle is zero
3)the frame may be inertial but the resultant force on the particle is zero
4)the frame may be noninertial but there is a nonzero resultant force.
(two of the above options are correct. which r those n why?)

thnx in advance

This sounds like your Homework. I am not going to do your homework for you.
 
im not asking u to solve anything...these r conceptual doubts
 
There are no 'doubts' in your question. What do you think the answers are?
 
amm...i have no idea abt the first two...i think the last one is (3) and (4)
