Static electricity Flashcards
What are electric forces
When ions create attractive and repulsive forces.
What are magnetic forces
Attractive and repulsive forces between two poles
What is electromagnetism
a force combing both electric and magnetic forces
What type of charge is an electron?
what type of charged is a Proton?
Electron = negative
Proton = positive
What are the 3 ways to transfer charges
Friction
Conduction
Induction
What is friction
Transfer of electron through rubbing objects
ETC. Balloon and hair, Sock and carpet
What is conduction
Transfer of electrons through direct contact
(can be friction as well)
Zapping someone after rubbing socks on carpet
Induction
Transfer of electrons through an electric field over a distance.
This creates polarization
ETC. The stick and paper dots thingy
What is polarization
When the electrons within a neutrally charged object shift their position relative to the protons
Simplified: when the protons move to one side of a neutrally charged object and the electrons move to the other side of the object
what is static discharge
sudden flow of electric charge between two objects
one thing zap onto another thing
ETC. lighting
