Fields and Field Lines
This type of charge would move in the direction of electric field lines. The opposite charge would move in the opposing direction.
positive
This type of charges will repel each other. The opposite will attract.
like charges
This is the law involving distance dependence shared between magnetic, gravitational, and electric forces.
the inverse square law
This value is electric potential energy per charge.
electric potential or voltage
The negative subatomic particles in an atom.
an electron
The electric field lines point outward from an object. The object has this type of charge.
positive
The charge of your brush after running through your hair
negative
This law states that the force between charges is proportional to the product of the charges and inversely proportional to the square of the distance.
Coulomb's Law
The flow of charge
The SI unit of charge. (1 electron is 1.602 x 10-19 of these!)
Coulomb (C)
The electric field lines point inwards towards an object. The object has this type of charge.
negative
When objects have charge, it is due to these subatomic particles.
electrons
This is the value of G in Nm2/kg2
6.67 x 10-11
The part of a simple electric circuit that resists electric current
a resistor
A pair of equal and opposite charge separated by a distance.
an electric dipole
This is the pole of a magnet that field lines point to. Field lines point out of the other pole.
south
This principle states that charge can be neither created nor destroyed.
charge conservation
When the distance between two charges is doubled, this is how much electric force is between them.
one fourth the electric force
The amount of current present when 5 V passes through a 10 Ω resistor
0.5 A
Increasing the distance between two charges will do this to the strength of the field between them.
decrease
Earth's north geographic pole is in line with this magnetic pole. (Note: Earth's magnetic field lines point from its south geographic pole to its north geographic pole.)
south
In metals, multiple atoms share electrons allowing them to flow freely, causing most metals to be this kind of material.
a conductor
Gravitational force can only attract. This is how electric force acts on an object.
Attract and/or repel
This would be the current needed to pass 15 V through a 3 Ω resistor.
5 A
A molecule with a negatively charged portion and a positively charged portion. One example is water.
a polar molecule
