Any material that allows electrons to flow through it easily. A good example is a metal.
conduction
conductor
induction
insulator
Any material that does NOT allow electrons to pass through it easily. Plastic, wood, glass and rubber are good examples.
Conductor
Conduction
Insulator
Induction
The particle that can move from object to object and can cause an object to become charged.
proton
electron
neutron
balloon
Grounding occurs when
a balloon is rubbed on fur
excess electrons are removed from an object when touched to something big and relatively neutral
the charges on an object become separated when brought close to a charged object.
electrons move from a more negative object to a less negative object
Charging by touching to another charged object.
grounding
conduction
induction
polarization
charging an object by creating regions of charge by bringing a charged object NEAR but NOT touching
conduction
friction
grounding
induction
When electrons rub off one object on to another to create a charge in both objects.
grounding
conduction
induction
friction
A static electricity machine
Coulomb's Machine
Van de Graff generator

An object becomes positively charged when....
electrons are removed
electrons are added
protons are removed
protons are added
Two balloons are each charged by rubbing them with animal fur. What will the balloon do when brought close to each other
induction
conduction
repel each other
attract each other
When I slide my feet across carpet, I pick up electrons from the carpet and I _______________.
gain mass and become positively charged
gain mass and become negatively charged
lose mass and become positively charged
lose mass and become negatively charged
Lightning and small arcs from the Van de Graff generator are examples of this.
phenomenon
grounding
induction
polarization
Metal are good conductors of electricity because
they always have a charge
they allow electrons to flow through them easily
they do not allow electrons to flow through them easily
they can be heated easily
When a charged object is brought close to but not touching another object, the second object is charged by
induction
conduction
friction
grounding
Which diagram illustrates what happens when a negative balloon is brought near a neutral wall?
A
B
C
D
Object A has a charge of +6 C and object B has a charge of -14 C. The charges are brought together so they touch. What will be the charge on each object after they touch?
A: - 6 C and B: +14 C
A: -14 C and B: +6 C
Both A and B will have -8 C
Both A and B will have -4 C
Two charges repel each other with a force of 4 N. What will happen if both charges are doubled?
the force quadruples and becomes 16 N
the force is cut in half and becomes 40 N
the force quadruples and becomes 1 N
the force doubles and becomes 8 N
According to Coulomb's Law if the distance between two charges triples, the force between them will
Also triple
increase by 9 times
decrease by 9 times (be 1/9 as much)
not be affected
Which set of charges will be most attractive if they are all placed 1 m apart?
+ 2 and +6
+ 2 and - 6
+4 and - 8
+ 4 and + 8
A and B have the same charge. Which charge has the greatest electric potential energy?
A, because it is + and is closer to the + rod
B, because it is + and is closer to the - rod
A, because + charges are repelled by + rods
B, because + it is closer to the negative rod
Charge A and B are both positive. Which feels the greater force?
A because it is further away from the charge
B because it is closer to the charge
A because it is a positive charge
B because it is a negative charge
How much work is done to transfer 0.32 C of charge through an electric potential difference of 18.0V?
5.76 Joules
56.25 Joules
0.018 Joules
18.32 Joules
