Welcome to PHYS2002! Physics I – Done! We are now all experts in mechanics. Mechanics Mass We never said what mass is, only how it behaves. This semester, we are concerned with something called charge . Electricity Charge *And just like in mechanics, E&M will not tell us what charge is, but only how it behaves. Like mass, charge is an intrinsic property of matter, and it comes in 2 types: 1 Positive and Negative

h 18 lectric Forces and Electric Fields Ch. 18 – Electric Forces and Electric Fields 18.1 – Electricity eview the standard model of the atom: Review the standard model of the atom: Nucleus *The SI unit of charge is the Coulomb [C]. e e Proton charge is positive: +1e = +1.602 × 10 -19 C lectron charge is negative: e = 602 0 - 9 2 Electron charge is negative: -1e = -1.602 × 10 19 C Neutrons are neutral: No charge
18.2 Charged Objects and the Electrical Force. *In nature, atoms like to have equal numbers of protons and electrons, so that their net charge is zero. These atoms are electrically neutral . Electrical charges can be transferred between different objects. For example: If we remove an electron from a neutral We can transfer electrons between to objects by o e ap e e eo e ae e c t o o u t a atom, we are left with a positively charged ion .
