TEKS:P.6A/B/C Coulomb's Law

2

Coulomb's Law: Vocabulary

Electrostatics:

The study of electric charges that can be collected and held in one place.

3

Coulomb's Law: Vocabulary

Neutral:

An object whose positive charges are exactly balanced by its negative charges.

4

Coulomb's Law: Vocabulary

Electric Insulator:

A material through which electric charge will not move easily.

5

Coulomb's Law: Vocabulary

Static Electricity:

Imbalance between positive and negative charges within a material.

6

Coulomb's Law: Vocabulary

Electric Current:

A flow of charged particles.

7

Coulomb's Law: Vocabulary

Electric Charge:

the amount of energy or electrons that pass from one body to another by different modes like conduction, induction, or other specific methods.

8

Coulomb's Law: Vocabulary

Attract vs. Repel:

Attract: a force that causes objects to move closer together.

Repel: to force something to move away or move apart from something else.

9

Coulomb's Law: Vocabulary

Coulomb's Law:

States that the force between two point charges varies directly with the product of their charge and inversely with the square of the distance between them.
