These are the two fundamental rules at the base of all electrical phenomena.
What is opposite charges attract and like charges repel?
100
The charging process by which the two objects being charged become equally, but oppositely charged.
What is charging by friction (Triboelectric charging)?
100
This person was the first to discover that lightning and electricity in the laboratory were the same phenomenon.
Who is Benjamin Franklin?
100
9 x 10^9 Nm^2/C^2
What is k?
100
The charge of an antiproton.
What is negative?
200
Objects that have as many protons as electrons.
What are neutral objects?
200
The process in which there must be a touch or a spark from the object doing the charging to the object being charged.
What is charge by conduction?
200
A device used to attract atmospheric charge and direct it safely into the ground.
What is a lightning rod?
200
He was the first to discover the law.
Who is Henry Cavendish?
200
Charge is a fundamental property that makes charged particles feel this.
What is the electric force?
300
The only charge that can move in a solid material.
What are electrons?
300
The process by which the object responsible for electrifying does not transfer any charge to the object being electrified.
What is charge by induction?
300
In the video, what piece of equipment was used to simulate lighting in the lightning-struck car experiment?
What is a tesla coil?
300
Coulomb's Law is very similar in form to this law.
What is Newton's Law of Universal Gravitation?
300
The magnitude of the electric force is proportional to this.
What is the product of the charges?
400
The two factors that affect the force between two electric charges.
What are the amount of charge and the distance between them?
400
This happens in the molecules of dust to explain why dust so readily sticks to television tubes. It also happens to your electroscope in the presence of a charged object.
What is charge polarization?
400
The charge in the ground directly under a negatively electrified storm cloud.
What is positive charge?
400
Of the three types of particles that make up an atom, this one does NOT feel the electric force.
What is the neutron?
400
The scale of electron grabbers to electron donors.
What is the triboelectric series?
500
An object is said to be charged if it lost or gained these particles.
What are electrons?
500
Upward electrical discharges above clouds that are difficult to see.
What are sprites?
500
Although atoms are usually neutral, an atom in this form will feel the electric force.
What is an ion?
500
In a field diagram, the strength of the electric field is given by this.
