First describe what a force is and what effects forces have

First, describe what a force is and what effects forces have on objects. Provide one or two examples of forces operating at a macroscopic scale to help you form analogies to describe atomic phenomena. Then describe the forces involved in holding matter together at the atomic level. Describe what would happen if various atomic forces disappeared? Also, provide a description of some of the forces between atoms that result in molecules and larger collections of atoms, and how these forces are important

Solution

Force changes the state of motion and state of rest , Force is a push or pull which creats acceleration , forces changes direction of the objects moving . force change shape of the objects, force is the capacity to do work.

Forces work at the macroscopic level prmarly is gravity which is responsible for the whole mass in the universe to stay in tact with out getting fly away , the same gravity makes stars , solar systems and helps the formation of planets.

The fource basic forces of nature are , Gravity , Electromagnetic , strong nuclear forces and weak nuclear forces, out of which gravitational forces works at macroscopic scale and rest of the threee works in microscopic scale on matter.

Electromagnetic force is responsible for holding all the atoms in molecules to gether ,and also the same force behind all the chemical reactions. the stong nuclear and weak nuclear forces are the backbone behind the binding of nucleons in nucleus.

Strong and weak nuclear force play key role in the formation of heavy nucleus from individual protons, electromagnetic forces are responsible for the formation of atoms , with out either stong nuclear and EM force atoms may not exist in our universe , and gravity plays the leed role for the formation of stars where the systhesis of all the nucleus takes places, with out gravity the universe may left with individual protons and electrons .

The residual attractive or repulsive forces between atoms, molecules, and surfaces, as well as other intermolecular forces are called vander waals forces, which arise due to electromagnetic fields, van der Waals forces are weaker than normal covalent ionic bonds which are short-range forces and should be considered only if the molecules are closer , these forces are important in the formation of macrosizd molecules in the formation fo liquids and protein stuctures and DNA.
