the study of stationary electric charges
electrostatics
a material that prevents or blocks the flow of electric charges
insulator
unit for electric charge
coulumb
when electrons in a neutral object move because of the electric field of a nearby charged object
polarization
a material that is sometimes acts as a conductor and sometimes acts like an insulator
semiconductor
can be positive, zero, or negative. determined by number of electrons gained or lost.
electric charge
when a charged object is brought near to a neutral
conducting object and forces electrons
within the conductor to migrate
induction
the positive particle in an atom
proton
a material that electric charges can flow through
easily
conductor
the negative particle in an atom
electron
what happens when a positively charged object comes close to a negatively charged object
attraction
when there is direct contact between materials that differ in their ability to give up or accept
electrons.
conduction
law that describes two objects total net charge before and after a reaction
conservation of change
what happens when a negatively charged object comes close to another negatively charged object
repulsion
when electrons transfer between two objects that are rubbed together.
friction
