The Rules
What a CHARGE!
Other Physics
Coulomb's Law
General Electrostatics
100
These are the two fundamental rules at the base of all electrical phenomena.
What is opposite charges attract and like charges repel?
100
A device used to attract atmospheric charge and direct it safely into the ground.
What is a lightning rod?
100

The quantity that is equal to 0 when an object reaches the top of its motion? Also, the thing that Lightning McQueen is - 

What is velocity/speed?

100
9 x 10^9 Nm^2/C^2
What is k?
100
Of the three types of particles that make up an atom, this one does NOT feel the electric force.
What is the neutron?
200
Objects that have as many protons as electrons.
What are neutral objects?
200

The charging process by which the two objects being charged become equally, but oppositely charged.

What is charge by friction?

200

Newton's second law of motion

F = ma

200

The meaning of a negative sign in the result of Coulomb's law

What is attractive?

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 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 contact?

300

This mode of heat transfer that does not require any mode of transportation.

Radiation

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 charge of an object or 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

The type of force (attractive or repulsive) felt between a negatively charged insulator and a neutral conductor

What is attractive?

400
The type of radioactive decay that does not effect the nucleus
What is gamma decay?
400

The resulting effect to potential energy when two negatively charged objects are moved away from each other.

What is decreasing?

400

The scale that tells us how good a material is at stealing an electron.

What is the triboelectric series or the electrostatic series?

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

This happens in the molecules of dust to explain why dust so readily sticks to television tubes. It also happens to a wall when a charged balloon gets near it

What is charge polarization?

500

What is the efficiency of a car which uses 30,000J of energy to gain 21,000J of kinetic energy?

What is 70%

500

What happens to the force between two objects when the distance increases by a factor of 6

What is the Force decreases by a factor of 36

500

In a field diagram, the strength of the electric field is given by this.

What is the density of the field lines?
