How does the electric force relate to the common contact forces people experience each day?

Electric force is the invisible superhero of the microscopic world, acting between charged particles to create attractions and repulsions. Just as a magnet can pull paper clips magically toward it, electric forces between atoms form the bonds that keep your furniture and your cell phone intact. Next time you sit on a chair or hold a laptop, remember that electric forces are doing the heavy lifting, holding everything in place! In daily life, we often encounter contact forces like friction, tension, and normal force without giving them much thought. These forces come into play, for instance, when you push a book across a table or lean against a wall. Interestingly, while you feel those forces, they fundamentally arise from the electric interactions between atoms in the surfaces in contact. So, whether you're walking, sitting, or carrying groceries, electric forces are in action, underlying all the contact forces you experience!
