5 Electric Charges and Fields

process by which an electrically charged object brought near a neutral object creates a charge separation in that object

• charging by induction
• static electricity
• polarization
• permittivity of vacuum

electron that is free to move away from its atomic orbit

• electron
• conduction electron
• neutron
• proton

material that allows electrons to move separately from their atomic orbits; object with properties that allow charges to move about freely within it

• insulator
• ion
• conductor
• dipole

total source charge composed of so large a number of elementary charges that it must be treated as continuous, rather than discrete

• volume charge density
• surface charge density
• linear charge density
• continuous charge distribution

SI unit of electric charge

• coulomb
• Coulomb force
• Coulomb’s law
• Coulomb's constant

another term for the electrostatic force

• coulomb
• Coulomb force
• Coulomb’s law
• Coulomb's constant

mathematical equation calculating the electrostatic force vector between two charged particles

• coulomb
• Coulomb force
• Coulomb’s law
• Coulomb's constant

two equal and opposite charges that are fixed close to each other

• insulator
• ion
• conductor
• dipole

physical property of an object that causes it to be attracted toward or repelled from another charged object; each charged object generates and is influenced by a force called an electric force

• electric charge
• electric field
• electric force
• electron

physical phenomenon created by a charge; it “transmits” a force between a two charges

• electric charge
• electric field
• electric force
• electron
