Charge and Coulomb's Law

Magnitude

Electrons and Protons have the same _____ of charge

Neutral

Atoms are electrically ______ meaning, they have no charge

Ion

If an atom gains or loses electrons, it gains a charge and becomes an

negative

Rubber objects almost always gain a ______ charge during rubbing operations.

Like charges repel while opposite charges attract

What is the Fundamental Law of Static Electricity

Charge is not created nor destroyed, merely transferred from one system to another

What is the Main Principle of Conservation of Charge

Conductors

The charge is carried through the material by the free electrons that metals have because of their metallic bonds.

Metals

What materials are usually classified as conductors?

Insulators

These substances have their electrons tightly bound in their chemical bonds.  The charge can’t go anywhere in these substances because there’s nothing to carry the charge

Not free to move

In an insulator, what is the range of movement of electrons?

where you put it

The electrons are not free to move.  When a charge is placed on an insulator, the charge stays where

Electrolytes

are liquid solutions that can conduct electricity.

Ions

•The electrolyte contains ____ that transfer charge.

Conduction and Induction

What are the two ways one can charge an object?

Charging by conduction

is a method of charging a neutral object by touching it with a charged object

Charging by conduction

“An object is given a charge – we rub a rubber rod with a rabbit fur.  The rod now has a negative charge.” This is an example of what type of charging technique?

Charing by induction

is a process that charges a neutral object without touching it to a charged object

Charing by induction

t's a type of wireless power transfer that uses electromagnetic induction. 

Coulomb

The basic standard unit of charge is called a

6.25×10^18

One coulomb is equal to the charge of _________ electrons or protons

-1.6×10^-19C , +1.6×10^-19C

The charge of a single electron is ______ and the charge of a single proton is?

Point charges

We will also assume that the charges are concentrated into a small area called?

attractive or repulsive

•The force between two charged objects can be either______ or _________, depending on whether the charges are like or unlike.

Superposition Principle

The resultant force on a charge is the vector sum of the forces exerted on it by other charges.

vector sum

The resultant force on a charge is the ____ ____ of the forces exerted on it by other charges.
