AI Thread Summary
Balanced forces do not change an object's motion, while unbalanced forces result in a net force that causes motion. The discussion highlights the ratios of gravitational force to other fundamental forces, indicating that gravity is the weakest force, having minimal impact at the atomic level. The confusion arises regarding how gravity interacts with atomic nuclei as their size changes. It is clarified that gravity's influence remains negligible compared to stronger forces, regardless of the atomic size. Understanding these concepts is crucial for grasping the principles of motion and force dynamics.

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.
