Electrostatics Flashcards
What does Electrostatics deal with?
It is the study of non-moving charges that are built up on the surface of an object.
What is the definition of charge?
Charge is the gaining or losing of electrons that causes a positive or negative charge.
How do we know that charge exists?
We can see how certain objects attract or repel each other.
What are electric fields?
Electric fields are regions in space where charged objects experience an electrostatic force.
What are two factors that affect the strength of the electrostatic force experienced between two charges.
The strength of the force depends on:
Distance and
Magnitude
Term for this definition:
The net charge of an isolated system remains constant during any physical process.
Law of Conservation of Electric Charge
What is the name of the force that is exerted between objects that are charged?
Electrostatic force
Definition of insulators.
Objects that don’t allow electricity to move through it/don’t allow electrons to travel through them.
Where can you find charge on a conductor?
Charge stays on the surface if the conductor.
How is the charge distributed on the conductor if it has equal sides and lengths?
Charge is evenly distributed. (Electrons)
How is the charge distributed on the conductor if it has unequal sides and lengths?
Charge is concentrated at the sharper end. Unevenly distributed.
What is elementary charge?
The amount of charge carried by one electron (-1.6x10^-19C)
What is Charge Quantisation?
The principle that the charge of any object is an integer multiple of the elementary charge.
Water is a polar molecule. T/F
Hydrogen atoms slightly more …
Oxygen atoms slightly more …
TRUE
Hydrogen atoms are slightly more POSITIVE
Oxygen atoms are slightly more NEGATIVE
How do objects become charged?
By friction
