Charges & the Electric Force
Micro-model of Charge, Q-transfer, Conductors vs. Insulators
Electric charges are all around us. They are responsible for many of the phenomena we see, including the true nature of the normal force. Some charges can move and some can reorient to create interesting effects.
Electric Forces & Coulomb's Law
Atoms are comprised of charges. The positively charged nucleus is attracted to the negatively charged electrons. Molecules, which are comprised of atoms, also bind together due to this charge related force of attraction. Solids and liquids, comprised of molecules, also bind together due to the electric force of charges. All forces we experience, except gravity, are due to the electric force.
