positive and negative
Repel
attract
E's from one object can be transferred to the other, leaving one object with extra e's (- charged) and the other object with less e's (+ charged)
Conserved because the e's gained by one object always equal the e's lost by the other object
Coulombs
-1.60e-19
+1.60e-19
yes
When the electrons can possess only certain discrete energy values
the smallest amount of charge possible
an integer multiple of the charge of one electron
materials in which charges can move freely
materials in which charges cannot move feely
can act as either a conductor or an insulator
by contact
it is grounded
all the electrons (without becoming charged)
electrons without becoming charged
the molecules of a neutral object so one side is positive and one is negative
polarizaton
there isnt a net charge
the charge spreads out evenly between the two objects and both objects should end up with half the org charge
in induction a conductor conductor is brought near a charged object and the like charges are repelled, so they move away from the charged object
the conductor will be left with the opp charge
FE= Kc q1 q2 / r (squared)
Coulombs constant = 8.99e9 Nm (squared) / C (squared)
the amount of charge on each object (Coulombs)
The distance between charges (meters)
The force is reduced by 1/4 th
The force is double the whole charge
