Coulomb's Law Flashcards
charging
giving an excess of +/- charge to a neutral object
conductor
charges move freely through these: copper, aluminum, tap water, etc.
insulator
charges can NOT move freely ex. wood, plastic, rubber band, pure water
polarization
rearrangement of charges
-results in non zero electric force
charge distance - force relationship
as the distance between 2 charges increases, the magnitude of force decreases
consistency w/ Newton’s 3rd law
if 2 charges q1 and q2 exert electric force on each other, the electric force F (2to1) on q2 exerted by q1 is the ACTION. Opposite is reaction
Principle of superposition (F1,net)
net electric force on charge q1 due to q2.. is the vector sum of electric forces on q1 due to individual charges q2, q3…
Shell Theories (1)
A charged particle outside the shell is attracted or repelled as if the shell’s charge were concentrated as a particle at its center
Shell Theories (2)
A charged particle inside a shell has no net force acting on it due to the shell.
Coulomb’s Law
quantification of the electric force between two charges at a distance apart
grounding
neutralizing charges
magnitude of charge transferred when identical spheres touch
find the average
