Question

Explain why common "contact forces" such as a person pushing on a wall are actually caused by the electric force. In your answer, you must discuss the role of subatomic particles in this interaction, whether the atoms in the person’s hand and the wall come into contact or not

Answer 1

are due to the fact that the electrons that are in one of the objects get close to electrons that are in the other object and since it has the same charge, inte

Step-by-step explanation:

The contact forces, such as friction or the push force, are due to the fact that the electrons that are in one of the objects get close to electrons that are in the other object and since it has the same charge, intense repuesive forces are formed that objects move. We can see that in these forces the electrons are still attached to the material and only electoral repulsion is what creates the force.

In the previous explanation, it is valid for all types of material, the only change occurs due to the strength of the bond, in the case of materials with free electrons, such as metals, the forces are small, so the sliding occurs for small bourgeois

In insulating materials such as rubber where the electronons are tightly bound, closer proximity is needed to move the electrons from their equilibrium position.
