electrostatics - CORRECT ANSWERS electric charges at rest
not in motion, as in electric currents.
attractive and repelling forces that exist between positive and negative electric charges.
electrical force - CORRECT ANSWERS force that one charge exerts on another
When the charges are the same sign, they repel; when the charges are opposite, they attract.
Like charges repel; opposite charges attract.
conservation of energy - CORRECT ANSWERS Energy cannot be created or destroyed
whenever something is charged, no electrons are created or destroyed. Electrons are simply transferred
from one material to another. Charge is conserved. No case of the creation or destruction of net electric
charge has ever been found.
ion - CORRECT ANSWERS A charged atom
,A positive ion has a net positive charge. A negative ion, an atom with one or more extra electrons, is
negatively charged.
an object that has unequal numbers of electrons and protons is electrically charged.
quanta - CORRECT ANSWERS The bundle of electromagnetic energy that is absorbed or
emitted by matter
quanta refers to tiny packets of energy, like indivisible pieces of candy. It's a way to describe how energy
can only be exchanged in specific amounts
static electricity - CORRECT ANSWERS form of electricity resulting from the imbalance
between positive and negative charges within a material that occurs when electrons (the negatively
charged particles in an atom) move from one material to another.
occurs when an object obtains a net amount of positive or negative electric charge, creating an
imbalance that wants to be returned to equilibrium.
Coulomb's Law - CORRECT ANSWERS electric force between charged objects depends on the
distance between the objects and the magnitude of the charges.
formula: magnitude of the electric force between two objects is equal to the coulomb's constant times
the charge on one object times the charge on the other divided by the square of the distance between
them
F= force exerted on one another(N)
K= Coulomb's constant(9.0 x 10^9 Nm^2/C^2)
q1= charge of one of the object (C)
q2= charge of another object (C)
, r= distance between them (m)
Coulomb - CORRECT ANSWERS SI unit of electric charge, 1C is equal to the total charge of 6.25
x 10^18 electrons.
a unit of electrical charge equal to the amount of charge transferred by a current of 1 ampere(a unit of
measure of the rate of electron flow or current in an electrical conductor) in 1 second.
one charge of 2.0C is 1.5m away from a -3.0C charge. Determine the force they exert on each other. -
CORRECT ANSWERS F= ?
K= 9x10^9Nm^2/C^2
q1= 2C
q2= I-3CI = 3C
r= 1.5m
Coulomb's constant - CORRECT ANSWERS strength of force between 2 charged particles, if a
pair of particles 1C were 1m apart, it would be 9 billion N, or the Coulomb's constant.
K= 9 x 10^9 Nm^2/C^2
or
9,000,000,000 Nm^2/C^2
If, for example, a pair of like charged particles of 1 C each were 1 m apart, the force of repulsion
between them would be 9 billion N. That would be more than 10 times the weight of a battleship!
Coulomb's constant is important because it quantifies the strength of the electrostatic force between
charged particles, allowing us to understand and predict the behavior of charged systems.
