Chapter 32 Flashcards
Charge
the electrical property which the mutual attractions & repelling behavior between electrons or protons is attributed
Conductor
materials, usually metal, that electric charge can flow
Conservation of charge
the principle that net electric charge is neither created or destroyed, but is transferable from on material to another
Coulomb
the Si unit of coulomb
Coulomb’s Law
the relationship among electrical force charges, and distance; the electrical force between two charges varies directly as the product of the charges and inversely as the square of the distance between them
F= k x q1 x q2 / d^2
Electrical force
- a force that one charge exerts on another
- charges w/ same sign repel
- opposite charges attract
electrically polarized
when one side of the atom or molecule is induced to be slightly more positive or negative than the opposite side
electron
a negatively charged particle that is one of the two kinds of particles found in the nucleus of an atom
electrostatics
the study of electric charges at rest
grounding
- allowing charges to move freely along a connection between a conductor and the ground
- charges move off or on by touching it
induction
the charging of an object without direct contact
insulator
a material that is a poor conductor of electricity
Proton
A positively charged particle that is one of two kinds of particles found in the nucleus of an atom
neutron
a electrically neutral particle that is one of the two kinds of particles that compose an atomic nucleus
Semi conductors
Materials that can be made to behave sometimes as insulators and sometimes as conductors
