Ch. 21:
    · Electric Field
        · consider test charge q0
        · electric force exerted on it is due to field from other charges
        · force per unit charge: E= F/q0
        · units of electric field
        · can switch around: F= q E (used often)
        · like gravitational field F = m g
        · also superposes
    · Electric Field of different situations:
        · point charge
        · dipole
        · infinite sheet
        · parallel sheets
        · line of charge
        · ring
        · disk
    · Electric Field Lines
        · helps to visualize E-field
        · higher density of lines indicates large magnitude
        · direction: away from positive charge
Introduction to Lab:
        · precision vs accuracy
        · uncertainties vs error
        · a quick measurement lab

How E&M fits into the big physics picture:
    · strong
    · everywhere
    · practical (question about life or death)
Assess/review physics/math/units skills
    · units
    · vectors
    · gravity
    · two dimensional motion
Ch. 21:
    · electric charge (or just charge)
    · electrostatics
    · attract/repel
    · nucleus, proton/electron (magnitude e), ion
    · conservation of charge
    · conductor / insulator
    · charging by (important to understand motion of charges for later)):
        · touching
        · induction
    · Coulomb's Law
        · just like Newton's (for gravity)
        · constants k and e
        · superposition
