static charge Flashcards
Static Electricity
Electricity that stays in one place
Current electricity
Moving electricity
How can an atom become charged?
Gaining or losing electrons
Insulators
Any material that prevents the charges to move freely… ex; rubber,plastic,glass,wood
Conductors
Any material that allows charges to move freely… ex; metals
Coulomb
Unit of charge
Grounding
Connecting electricity with the ground so that it can disperse
Force
A push or pull on an object
Electric force
A push or pull between charged objects, can be applied without contact (action-at-a-distance)
what are the 3 laws of attraction?
- Opposite charges attract
- Like charges repel
- Charged objects attract neutral
Charging by conduction
Creating a charge in an object by direct transfer of electrons (contact)
Charging by induction
Occurs when an electric charge develops on an object due to the presence of a nearby object (no contact)
Acetate charge
Positive
Vinyl charge
Negative
Metre stick charge
Neutral
