Homework Help Overview

The discussion revolves around the application and validity of Newton's laws in various contexts. Participants are exploring whether there are situations where these laws do not hold true, particularly in relation to kinematic equations.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Some participants question the original poster's understanding of the homework requirements and the necessity of demonstrating personal effort. Others inquire about specific scenarios where Newton's laws may not apply, seeking clarification on the topic.

Discussion Status

The conversation reflects a mix of frustration and attempts to guide the original poster towards adhering to forum rules. While some participants express the need for the original poster to show their own efforts, others are attempting to redirect the focus back to the core question about Newton's laws.

Contextual Notes

There is an ongoing tension regarding the forum's rules about effort in homework threads, with reminders issued to the original poster about the expectations for participation. The discussion also touches on the perceived tone of responses, which some participants find disrespectful.

New poster has been reminded to show their work on schoolwork problems
Homework Statement
Existing situations in which Newton's laws are not fulfilled? If so, which ones?

In the case of the formula f = m.a, there must always be a constant acceleration, otherwise this equation would not be valid?
In the case of inertia in the same way, if it is at rest, is it not valid?
and in the second law there must be force? Please clarify these doubts, and if I am wrong in something let me know

Please I require solutions to this question about Newton's laws
thank you

You need to make an effort yourself here.

Was that this question by any chance?

No is the same, in this forum I want to know about Newton laws

Don't be rude, I'm just asking you for an opinion on the subject, if you don't like it, don't answer, period.

If you are just going to screw around, you're not likely to get any help

Also, to reiterate post #2, you have to make some effort yourself. We are not here as a Q&A forum.

He's not being rude. He's pointing out that the forum rules require you to show your own effort first for a homework thread. You can't just "ask an opinion".

Same response here; you are being reminded of the forum rules, and that is not "rude".

If you cannot show any effort yourself, this thread will be closed.

No está siendo grosero. Señala que las reglas del foro requieren que primero muestres tu propio esfuerzo para un hilo de tarea. No se puede simplemente "pedir una opinión".
Misma respuesta aquí; se le recuerda las reglas del foro, y eso no es "grosero".

Si no puede mostrar ningún esfuerzo por sí mismo, este hilo se cerrará.

yo know the rule ,but if they start to tell me that " just going to screw around " I'm taking it as an offense I developed the question if you can SEE IT CLEARER ABOVE IN THE PUBLICATION.

This might help.

Point #4.

What level of schoolwork requires you to find/not-find examples of Newton's Laws being invalid ?

Then you should be following it, not complaining about what other people are saying.

Since you have failed to follow the rule despite repeated requests, this thread is closed.
