In summary: This is demonstrated in Newton's first law of motion, also known as the law of inertia. An example would be a book sitting on a table. The gravitational force is acting on the book, but it is balanced by the normal force of the table, resulting in a net force of zero and no motion. However, if the book is pushed with a force greater than the normal force of the table, there will be a net force and the book will move.

(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.

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.
 

FAQ: How Do Balanced and Unbalanced Forces Affect Object Motion?

What are the four basic forces?

The four basic forces are the strong nuclear force, the weak nuclear force, electromagnetism, and gravity. These forces govern the interactions between particles at the subatomic level.

What is the difference between the four basic forces?

The strong nuclear force is responsible for holding the nucleus of an atom together, the weak nuclear force is involved in nuclear decay, electromagnetism is responsible for the interactions between charged particles, and gravity is responsible for the attraction between masses.

How do the four basic forces interact with each other?

The four basic forces interact with each other in different ways. The strong nuclear force and the weak nuclear force are responsible for interactions between particles within the nucleus of an atom. Electromagnetism and gravity are responsible for interactions between particles outside of the nucleus.

What are some everyday examples of the four basic forces?

The strong nuclear force is responsible for keeping the protons and neutrons together in an atom's nucleus. The weak nuclear force is involved in radioactive decay, such as in nuclear power plants. Electromagnetism is responsible for electricity, magnetism, and the interactions between atoms in everyday objects. Gravity is responsible for keeping us grounded on Earth and the movement of celestial bodies.

How do scientists study and understand the four basic forces?

Scientists use a variety of methods, such as experiments and mathematical models, to study and understand the four basic forces. Particle accelerators, such as the Large Hadron Collider, allow scientists to study the behavior of particles at high energies. Theories, such as the Standard Model, help to explain and understand the interactions between particles and the four basic forces.
