Questions About Objects Touching?

In summary, the conversation discusses the concept of electromagnetic force and its role in keeping objects from physically touching. It is mentioned that the force can be extended over larger distances, but this is unlikely due to the inverse square relationship and other factors such as electron bonding. It is also suggested that changing the laws of physics could have major consequences on reality and the properties of matter.

When two objects are touching, it`s really electromagnetic force repelling the two objects (so the atoms never actually touch), right? Well, what happens if this force can be extended over larger distances? For example, a brick can be touching the floor without being close to it? In theory is this right?

Well the electromagnetic force dies off as an inverse square, so this probably wouldn't work. Also, the situation is more complicated than classical Coulomb repulsion. You've got electron bonding going on, as well as other forces that contribute to the macroscopic effect that we see in rigid objcts.

do you mean what would happen to human reality if you changed this law of physics?
perhaps a 1/R relationship instead?

Yes, as tot points out, if you change the laws of physics, you can do anything you want.

If you try to change the 'laws of Physics' you ain't got Physics any more. One of the first things to go wrong would be the Earth's orbit; it couldn't be an ellipse / stable. Also, Chemistry would be all to hell . . . . . .
 

1. What is the definition of "objects touching" in science?

The term "objects touching" refers to two or more physical objects coming into contact with each other.

2. How does the concept of objects touching relate to the laws of motion?

The concept of objects touching is closely related to Newton's laws of motion, specifically the third law which states that for every action, there is an equal and opposite reaction. When objects touch, they exert forces on each other in opposite directions.

3. Can objects touch without actually physically touching?

Yes, objects can appear to touch without actually making direct contact with each other. This is known as contact force, where the objects are separated by a small distance but still exert forces on each other.

4. How do scientists study the interactions of objects touching?

Scientists use various methods such as experiments, simulations, and mathematical models to study the interactions of objects touching. They also use tools like force sensors and motion detectors to measure the forces and movements of objects.

5. What are some real-life applications of understanding objects touching?

Understanding objects touching has many practical applications in fields such as engineering, physics, and materials science. It is crucial in designing structures and machines, predicting the behavior of materials under stress, and creating new technologies such as touch screens.
