Electrostatics Flashcards
What is charge?
A property of matter
What are electrostatic properties?
About electric charges, the electric field around them and the forces in between them
What does all matter contain?
negative and positive charges
What is the symbol of electric charges and what is it measured in?
Symbol = Q
Measured in Coulombs (C)
What is the definition of electric field?
A region of space in which an electric charge experiences a force
Describe the connection between charges?
Like charges repel and opposite charges attract
What does the connection between charges depend on?
Distance between charges and the amount of charge they have
How can electrons be transfered?
By rubbing objects together
How do objects get electrically charged?
When they gain or lose electrons
Explain how insulators influence electrical charge?
Not free to move easily
Rubbed to transfer electrons
Explain how conductors influence electrical charg?
Free to move easily
Transferred by touch
What is the definition of polerisation?
Bring together something charged and neutral
Explain polerisation?
neutral objects will have 2 pole: positive and negative
Positive will attract electrons
negative will repel electrons
What is the law of conservation of charge?
The net charge of an isolated system remains constant during any physical process. the total number of electrons in the system stays constant
Explain the process of distribution of charge?
When identical metal spheres touch, the electrons will flow from A to B until the electrons are evenly distributed. After touching each sphere will now have the same charge
