Two kinds of electric charge: positive and negative Two kinds of electric force: attractive and repulsive Note: this is in contrast to gravitational force where mass only attracts Building Blocks of Matter Conductors: Insulators: Electrons free to move Electrons don’t/cannot move (metals) (plastics) Coulomb’s Law​ (1785) ex) r^ determines direction F1,2​nd F​ 2,1​Newton’s 3rd Law pairs! If the resultant number is: ​positive → force is repulsive negative → force is attractive Uni
