What surrounds any charge or group of charges?
An electric field.
Describe an electric field.
An electric field extends outward from every charge and permeates all of space.
What surrounds a proton?
Electrons
What are field lines?
A series of lines to indicate the direction and relative strength of an electric field. Start on positive and end on negative.
If a hollow metal sphere has a large charge, what will be the relative strength of the electric field inside the sphere?
The strength of the electric field will be 0.
Where does excess charge reside on a spherical conductor.
On the outer surface.
Explain charging by friction.
When different materials are rubbed together, electrons can be transferred from one material to another.
Explain charging by conduction.The charging of a neutral object by touching the object with a charged object.Explain charging by induction.By bringing a charged object close to a neutral object, you can cause the electrons in the neutral object to move away from or towards the charged object.What is charge polarization?It is a slight shift of positive and negative charges in opposite directions.Why does a person's hair stand out when in contact with a Van de Graaff generator?Because of the loose electrons are transferred from the Van de Graaff through the person and goes up to the trands of hair where the exces electrons are trying to be released.Describe the electric field present between two oppositely charge metal plates.What is the underlying force in all chemical reactions?electrical forces.Electric Force: -Symbol -UnitUnits: Newtons (N)Charge: -Symbol -Unit-Q -CElectric Field: -Symbol -Unit-E -N/CCoulomb's Constant -Symbol -UnitSymbol: k Unit: N*m^2/C^2When are electrical forces between charges the strongest?When they are closest.What is Coulomb's law?Electrical force between 2 charges varies directly as the product of the charges and inversely as the square of the distance between.If two charges are separated by a certain distance and the distance is doubled, what happens to the force between the charges?It is quartered, 1/4th.If two charges have a charge of 2.0 C and the charge on one is doubled , what happens to the force between the charges?It is doubled.If two charges have a charge of 2.0 C and the charge on both is doubled, what happens to the force between the charges?It is quadrupled.What is an ion?A charged atomWhat is the charge on a non-ionized atom?zeroWhy is a positive ion positive?Loss of electronsWhat is conservation of charge?Where charge can not be created or destroyed.How are electrical forces and gravitational forces alike?Both have the a force between two charges. Proportional to the inverse of the square of separation.How are electrical forces and gravitational forces different?the constants.Why does an insulator insulate?Because they do not conduct charge.What property of a conductor makes it a good conductor?How well it conducts energy and how easily charge is transferred.Two charged particles held close to each other are released. As they move, the force on each particle increases. Therefore, the particles have...?opposite charges and are being attracted.Two charged particles held close to each other are released. As they move, the velocity of each increases. Therefore, the particles are...?charges cannot be determined, not enough information given.
