Which forces hold thing together(water, ice, desk,...). Are they just molecular forces(electric or electromagnetic) or there is something else?
kapital said:Where?
kapital said:And second what does give materials or any substance its strengt(are that molecular forces)?
kapital said:And what forse is need to tear paper?
kapital said:Yes, but is it possible to calculate(knowing molecular structure and geometry), how much that force is?
Atoms hold things together through the forces of attraction between their positively charged nucleus and negatively charged electrons. These forces are known as electromagnetic forces.
Gravity is the force that holds larger objects like planets, stars, and galaxies together. It is the result of the mass of an object and its distance from other objects.
Strong nuclear force holds the nucleus of an atom together by binding protons and neutrons together. Weak nuclear force is responsible for radioactive decay which can change the number of protons and neutrons in an atom.
Molecular bonds, also known as chemical bonds, hold atoms together to form molecules. These bonds are formed through the sharing or transferring of electrons between atoms.
Friction is a force that resists the motion of objects when they come into contact with each other. This force can hold objects together by preventing them from sliding or slipping apart.
