What a CHARGE!
Proportional Reasoning
Coulomb's Law
Electric Fields and Potential
100
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?

100

The force between two charges depends on these factors. (ALL OF THEM)

The magnitudes of the charges and the distance between them.

100
9 x 10^9 Nm^2/C^2
What is k?
100

The Ratio of Force Per Unit Charge

Electric Field Strength/Intensity

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 1C and a 3C charge exert electric forces on one another.  How does the force on the 1C Charge Compare to the force on the 3C charge?

They Are equal

200

Generally speaking the force between charges _______ when the distance between them increases

Decreases

200

The Ratio of energy per unit charge

Electric Potential/Voltage

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

If a charge is doubled, how will the force on it be affected?

It will double

300
Coulomb's Law is very similar in form to this law.
What is Newton's Law of Universal Gravitation?
300

The ratio of charge to electric potential difference across parallel metal plates

Capacitance

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

If the distance between charges is tripled, how will the force between the charges be changed

the force will be 1/9th as strong.

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

What effect does the test charge have on the electric field

The test charge has no effect on the electric field

500
An object is said to be charged if it lost or gained these particles.
What are electrons?
500

This type of charging results in the ground and clouds having opposite charge.  The results can be shocking

What is induction?

500

If the distance between charges is quadroupled, while both of the charges are doubled, the new force will be ___as much

one fourth

500
Although atoms are usually neutral, an atom in this form will feel the electric force.
What is an ion?
500

Two positive Charges have the most potential energy under what conditions?

When they are close together
