Vocabulary
The study of electric charges at rest
What is electrostatics?
Positively charged particle located within the nucleus of an atom.
What is a proton?
The charge on an atom that loses electrons.
What is positive?
In electric field drawings for a positive charge the arrow points this way.
What is away from the charge?
a law stating that like charges repel and opposite charges attract, with a force proportional to the product of the charges and inversely proportional to the square of the distance between them.
What is Coulomb's Law?
Fundamental electrical property to which the mutual attraction or repulsion between electrons and protons is attributed.
What is electric charge?
two types of particles located within the nucleus.
What are protons and neutrons?
The charge on a neutron.
What is zero net charge?
used to represent field lines.
What are vectors?
According to Coulomb's Law, given 2 fixed charges, if the distance is doubled the force will do this.
What is 1/4 Force?
The force that one charge exerts on another.
What is Electric Force?
Force that keeps protons located within the nucleus of an atom.
Strong Force
When we charge an object by indirect contact.
What is induction?
reason electric field lines extend from (+) to (-) charged objects.
What is a positive "test Charge"?
According to Coulomb's Law, given 2 charges, if one charge triples in magnitude, the force will do this.
What is triple in magnitude?
Principle that net electrical charge is neither created nor destroyed but is transferable from one material to another.
What is conservation of charge?
an atom with a net electric charge due to the loss or gain of one or more electrons.
What is an ion?
Charge on a single electron (note: answer must be stated with the correct units)
-1.602*10-19 C
method by which electric field lines depict the strength of force a charge will feel
What is the density or number of lines surrounding the charge?
What is the equation for coulomb's law?
F=(kq1q2)/r2
Force field that fills space around every electric charge or group of charges.
What is electric field?
an orbit followed by electrons around an atom's nucleus
the number of electrons that make up a charge of -8.01*10-19 C
What is 5 electrons?
the unit for electric field strength.
what is N/C?
The value of k. (note: answer must include units)
What is 9*109 Nm^2/C^2?
