Electric Charge, Coulomb’s Law, Electric Fields, and Flux Flashcards
Module 1
The ancient Greeks before discovered the concept of gaining a net electric charge through rubbing _____
and _____.
amber and cloth
The word electric is derived from the word “________” meaning amber.
electron
Static electricity is an imbalance of ________ charges within or on the surface of a material
electric charges
The algebraic sum
of all electric
charges in any
closed system is
________.
constant
This is the force that enables bits of paper to stick to
a freshly rubbed plastic comb, or the jolt that you feel
when you electrocuted with ______ ___________.
static electricity
If an electric charge can be transferred
through a specific material, that material is
called a _________.
CONDUCTOR
However, if a material does not permit the
transfer of charge it is called an _________.
INSULATOR
Occurs on a neutral object when a charged
object is in contact with it.
Conduction
Electrons transfer to the object making it the same ______.
charge
During __________, the same charge is created in a neutral
object.
conduction
Charging by conduction is considered as _________ since
electrons move to the new object until that object is
grounded.
permanent
- Requires contact
- Same Charge
- Permanent with electron transfer
Conduction
“The magnitude of the electric force between two point
charges is directly proportional to the product of the charges
and inversely proportional to the square of the distance
between them.”
Coulomb’s Law
In the coulomb’s law equation q1
and q2 are ___ charges.
two
What is the Coulomb’s Law constant for air is?
9.0x10^9(Nm^2/C^2)
What does this formula belong:
F = lkq1xq2/d^2
Coulomb’s Law
k = 9.0 𝑥 10^9 𝑁𝑚^2/𝐶^2
the constant k
