 * 1) Electric Field – an area of influence due toelectric charge between two or more objects directly proportionally to the sizeof the charge and inversely proportional to the distance squared
 * 2) Electric Force- the amount of force an object (neutralor charged ) exerts when it is attracted or repelled
 * 3) Electric Charge- the charge of the mostprevalent sub atomic particle over another making more attractive or less
 * 4) List 4 Methods of charging a neutral object
 * Polarizing (not really )
 * Conduction
 * Induction
 * Friction

Work to move a particle agaisnt gravity= energy making if have electri potential energy Energy possesed by a charge de tolocation in an electric field work done = change in potential energy Analogy 1: You go clothes shopping you spend 100 dollars, did i spend alot of money? I bought a pair of socks? Alot i bought a 5 pairs of Guess Jeans? Not Alot. It relative to what you gor for money. Electric Potential Energy ( per item price ) Potential Energy ( total price )

In order to have a light bulb light it must be apart of a continuous circuit connected to a batter ( in this case usually just a source of power ) it must be from tip to ribbed part or vice versa the position does not matter.
