1
Q

Static charge

A

Electricity that stays in one place

2
Q

Current electricity

A

Moving electricity

3
Q

Insulators

A

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

4
Q

Conductors

A

Any material that allows charges to move freely

Examples: metals

5
Q

Coulomb

A

Unit of electric charge

6
Q

Grounding

A

Connecting electricity with the ground so that it can disperse

7
Q

Force

A

(F) a push or pull on an object

8
Q

Electric force

A

(FE) a push or pull between charged objects.

-can be applied without contact: action at a distance

9
Q

Factors influencing effects of electric force

A

Amount of charge: increase charge, FE ⬆️

Distance between objects: increase distance, FE ⬇️

10
Q

Laws of attraction and repulsion

A
  1. Opposite charges attract
  2. Like charges repel
  3. Charges objects attract neutral
11
Q

Charging by conduction

A

Creating a charge in an object by direct transfer.

-contact

12
Q

Charging by induction

A

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