Electricity that stays in one place
Any material that prevents/impedes the charges to move freely.
Examples: rubber, plastic, glass, wood.
Any material that allows charges to move freely
Unit of electric charge
Connecting electricity with the ground so that it can disperse
(F) a push or pull on an object
(FE) a push or pull between charged objects.
-can be applied without contact: action at a distance
Factors influencing effects of electric force
Amount of charge: increase charge, FE ⬆️
Distance between objects: increase distance, FE ⬇️
Laws of attraction and repulsion
- Opposite charges attract
- Like charges repel
- Charges objects attract neutral
Charging by conduction
Creating a charge in an object by direct transfer.
Charging by induction
Occurs when an electric charge developed on an object due to the presence of a nearby charged object.
