Electrostatics Electricity at rest
Electric Current The motion of electric charges
Name two possible charges on a charged particle. Protons, Electrons
Atom smallest component of an element
Charging by contact when a charged rod is placed in contact with a neutral object, some charge will transfer to the neutral object
Charging by induction when you bring a charged object near a conducting surface and the particles become rearranged
Conductor a device designed to transmit electricity, heat, etc.
Coulomb unit of electrical charge equal to the amount of charge
Electrically polarized one side of the atom is induced to be slightly more positive than the oposite
insulator material with negligible, thermal, or electrical conductivity.
ion particle that is electrically charged
Protons positively charged
Electrons negatively charged
An electric force can either be.. attractive or repulsive
What is known about electrons? Repels other electrons. All electrons identical.
Compare contrast protons and neutrons neutron has a slightly greater mass than a proton
What is important about a normal atom? There is no net charge, there are as many electrons as there are protons.
Which electrons are most easily lost? the outermost electrons
What is an ion? A charged atom
What is the conservation of charge? electrons are not destroyed, but transfered
When does an object become charged? It gains protons
What are two methods of charging? Charging by friction, Charging by contact.
Grounding allowing charges to move freely along a connection between a conductor and the ground(stopping the charge)
What is lighting? an example of induction
Why are metals good conductors of heat and electricity? It's electrons are flowing further away from the nucleus, which makes them easier to transfer
