1

Static charge

Electricity that stays in one place

2

Current electricity

Moving electricity

3

Insulators

Any material that prevents/impedes the charges to move freely.
Examples: rubber, plastic, glass, wood.

4

Conductors

Any material that allows charges to move freely
Examples: metals

5

Coulomb

Unit of electric charge

6

Grounding

Connecting electricity with the ground so that it can disperse

7

Force

(F) a push or pull on an object

8

Electric force

(FE) a push or pull between charged objects.
-can be applied without contact: action at a distance

9

Factors influencing effects of electric force

Amount of charge: increase charge, FE ⬆️
Distance between objects: increase distance, FE ⬇️

10

Laws of attraction and repulsion

1. Opposite charges attract
2. Like charges repel
3. Charges objects attract neutral

11

Charging by conduction

Creating a charge in an object by direct transfer.
-contact

12

Charging by induction

Occurs when an electric charge developed on an object due to the presence of a nearby charged object.
-no contact
