◉Electric force . Answer: The force of attraction or repulsion on a
charged particle that is due to an electric field
-Units: N
-like charges repel, opposite charges attract
-vector (magnitude and direction)
-fundamental charge: e= 1.60E-19 C
Also, Fe=ma=qE
◉ϵ₀ epsilon naught . Answer: permittivity of free space
"how easily empty space forms an electric field"
8.85E-12 C^2/ N m^2
◉k coulombs constant . Answer: 8.99E+9 N m^2/C^2
◉Electrostatics . Answer: The study of electric charge and electric force
at rest (not in motion (static))
, ◉Conservation of charge . Answer: Electric charge is neither created nor
destroyed. The total charge before an interaction equals the total charge
after.
◉Coulomb's law . Answer: The relationship among electrical force,
charge, and distance
-If the charges are alike in sign, the force is repulsive; if the charges are
unlike, the force is attractive.
-Coulomb (C) is the SI unit of electric charge.
-1 C is equal to the total charge of 6.25 x 10^18 electrons.
-Electric forces between charges is strongest when the charges are close
together
-The electrical force between electric charges depends only on their
magnitude (strength of charge) and separation distance
◉Conductor . Answer: Any material that has free charged particles that
easily flow through it when an electrical force acts on them.
◉Insulator . Answer: A material that does not contain free charged par-
ticles and through which charge does not easily flow.
◉Semiconductor . Answer: A material with properties that fall between
those of a conductor and an insulator and whose resistance can be
affected by adding impurities.
