Homework Help Overview

The discussion revolves around the effects of balanced and unbalanced forces on object motion, with a focus on gravitational force compared to other fundamental forces. Participants explore the implications of these forces at atomic levels and their influence on motion.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants question the implications of the ratios of gravitational force to other forces, particularly in relation to atomic nuclei. There is also a discussion about the definitions of net force and its role in causing motion or changes in motion.

Discussion Status

The discussion includes attempts to clarify concepts related to forces and motion. Some participants provide insights into the relative strengths of forces, while others seek clarification on specific questions and concepts. There is no explicit consensus, but various interpretations and lines of reasoning are being explored.

Contextual Notes

Participants express confusion about posting questions and adhering to the forum's guidelines. There is mention of the need to understand the role of net force in motion, with some participants emphasizing the weakness of gravitational force at atomic scales.

Homework Statement

Homework Equations

The Attempt at a Solution

 
Physics news on Phys.org
(a) What is the ratio of the strength of the gravitational force to that of the strong nuclear force? (b) What is the ratio of the strength of the gravitational force to that of the weak nuclear force? (c) What is the ratio of the strength of the gravitational force to that of the electromagnetic force? What do your answers imply about the influence of the gravitational force on atomic nuclei?

a) 10^-38
b)10^-25
c) 10^-36

I do not understand the last part of part c. Is it that as the atomic nuclei gets smaller or larger, the gravitational force remains the same. Or is it that it was a greater force and feels more by gravity as atomic nuclei is smaller.

And your question is?
Sorry I am new and don't know how to post the question and answer.
 
you can edit your first post and follow the template provided.

I think they want you to notice that gravity is the weakest of the four forces and has virtually no effect at atomic levels.
 
Dhooy7,
Please don't use SIZE tags in your post. The fonts size is perfectly legible already.
 
Sorry I didn't try.
 
5. Which statement is correct? (a) Net force causes motion. (b) Net force causes change in motion. Explain your answer and give an example.

So, what is your answer to this going to be? Explain why.

Causes motion because two exact forces can act on an object and not move it. If the forces are unbalanced and the net force is not zero, then the object will move.
