test #1 Flashcards
the build up of positive or negative charges on an object.
Static electricity
a push or a pull
Force
smallest unit of matter. It contains protons, neutrons and electrons
Atoms
to push something away or move apart
Repel
to pull together
Attract
a material that allows electricity to pass through easily.
Conductor
a material that DOES NOT allow electricity to pass through easily.
Insulator
the process of creating an electric charge on an object by rubbing it against another object.
Friction
has a positive charge
protons
has no charge
neutrons
has a negative charge
electrons
The two subatomic particles found in the nucleus of an atom
protons and neutrons
the subatomic particles found in the outer orbit of an atom
electrons
which type of charging is when electrons are wiped from one object onto another?
Friction
Which type of charging is when electrons move from one object to another by direct contact?
conduction
when a charged object is held near an uncharged conductive material causing the object’s charges to rearrange?
induction
when an object is positively charged it…
loses electrons
when an object is negatively charged it…
gains electrons
objects with opposite charges will…
attract each other
objects with the same charge will…
repel each other
