1 - Electrostatics

In the early 600 B.C., ancient Greeks noticed when _____ and _____ were rubbed together, the would become "attractive".

1. amber

2. fur

He was the first recorded investigator of such ability of amber.

Thales of Miletus

He found out that many other substances when rubbed against another substance have this ability of amber.

William Guilbert

The Greek word for amber is "_____" which means "electrics".

elektron

Who studied "static electricity" in the 1750's?

Benjamin Franklin

Benjamin Franklin imagined electricity as being a type of _____ present in all matter.

invisible fluid

When matter contained too little electricity, it was _____ charged. When it had an excess, it was _____ charged.

1. "negatively"

2. "positively"

It refers to the build-up of electric charge on the surface of objects.

Static Electricity

It is the property of matter that creates electric and magnetic forces and interactions.

Electric Charge

It is the study of all phenomena associated with charged bodies at rest. It deals with the forces created by unmoving charges.

Electrostatics

What are the points in Microscopic View of Charge? (3)

1. Everything is made up of atoms.

2. Electric charges exist within atoms.

3. Subatomic particles of atom (Electron, Proton, Neutron)

It is the charging method when two objects or materials rub against each other and transfer electrons due to electron affinity.

Charging by Friction

It is the charging method when a charged object is brought near the conductor, causing charge redistribution.

Charging by Induction

It is the charging method when two objects touch, allowing electrons to flow from one to another.

Charging by Conduction

Give two examples of charging by friction.

1. Combing hair

2. Rubbing a balloon on cloth

Give two examples of charging by induction.

1. Thunderstorm

2. Lightning

Give an example of charging by conduction.

Charging a phone

Acquiring charge is a process of what?

transferring electrons

All (-) and all (+) are respectively identical in what?

mass and charge

A proton is equal in mass to a neutron, but _____ more massive than (-).

2000x

How do positive and negative charges work?

Like charges repel and opposite charges attract.
