01-05 Flashcards
p+ charge and n0 charge are found in the ______
neuclus
the only time a proton/neutron leaves an atom is when the atom is _______?
radioactive
negative charge are found outside the ?
necleus
neutal atoms or objects have equal
protons and electrons
+vely charged atoms have more?
protons than electrons
-vely charged atoms have more?
electrons than protons
materials that attract other materials are rubbing one another are?
charged
charged materials occur beacuse?
electrons move from one object to another
a neautral object has equal amounts of?
+ve and -ve atoms
what is static electricity
charges that remain stationary on the surface of an object
what is electrostatics?
the study of static charge
like charges ?
repeal each other
opposite charges ?
attract eack other
what can a charged object attract?
attract a neutral object
what is an insulator?
electrons cnnot bypass or move
what type of charge builds up on an insulator?
+ve or -ve
what is a conductor?
electrons can move freely
to charge a neutral object is by using
friction
charging of friction is the transfer of what?
is the transfer of e- between 2 neutral objects when they rub together
induction can be?
temp or permanenent
charging by induction:
when a charged object is brought close to a neutral object
do the e- move in induction charged materials
yes no protons move
giving a object a temporary charge by induction is called
induced charged separation”
giving an object a permanenent charge thro induction requires a ?
ground
when a -ve rod is brought to a n0 rod, what happens?
the +ve charges come to the -ve rods area
charging with conduction:`
occurs when an already charged object touches another object with dissimelar charge
what happens when a charged object touches a neutral object (conduction)
both objects will have the charge that came at it
what happens when two objects touch each other conduction
they will both become the same charge or neutral
what is grounding?
when a charged object is made neutral by coming into contact with a large neutral object
what is the symbol for grounding?
