Term
chemcial energy
Definition
energy stored in chemical bonds
Term
circuit
Definition
a path through which electricity can flow
Term
conduction
Definition
transfer of energy between objects that are touching
Term
conductor
Definition
a substance, such as metal, that conducts or transfers energy quickly
Term
convection
Definition
transfer of energy through currents, such as in liquids or gases
Term
electrical energy
Definition
energy that travels in waves, such as UV radiation; can be thought of as a combination of electrical and magnetic energy
Term
energy
Definition
the ability to do work
Term
friction
Definition
a force that oppposes motion between two surfaces that are touching
Term
heat
Definition
the transfer of thermal energy between objects with different temperatures
Term
insulator
Definition
a material, such as wood, that does NOT transfer thermal energy quickly
Term
kinetic energy
Definition
the energy an object has due to its motion
Term
Law of Conservation of Energy
Definition
states that while energy may be changed from one form to another, energy is neither created nor destroyed
Term
load
Definition
any device on a current that uses electrical energy to do work; ex - light bulb
Term
mechanical energy
Definition
the total of potential and kinetic energy exerted on an object
Term
nuclear energy
Definition
energy stored in the nucleus of an atom as a result of strong nuclear forces
Term
nuclear fission
Definition
a process in which the nucleus of an atom is split apart to produce two smaller nuclei and a large amount of energy
Term
nuclear fusion
Definition
process in which two smaller nuclei are joined together to produce a large amount of energy
Term
parallel circuit
Definition
circuit that offers more than one path for the flow of electric current
Term
potential energy
Definition
stored energy; energy of position
Term
radiation
Definition
the movement of energy through space; transfer heat without matter
Term
resistor
Definition
an object added to a circuit that resists the flow of electric current by producing a voltage drop when currents pass through it
Term
series circuit
Definition
a circuit that provides only one possible path for the flow of electric current
Term
sound energy
Definition
energy given off by vibrating object
Term
static electricity
Definition
the buildup of electric charges on an object
Term
switch
Definition
a device used to control the flow of current through a circuit
Term
temperature
Definition
measure of the average kinetic energy of the particles in a sample of matter; how hot or cold
Term
thermal energy
Definition
the total amount of energy in all of the particles contained in a sample of matter
Term
vacuum
Definition
empty space
Term
voltage
Definition
a measure of potential difference; term used to describe how bing of a "push" electrons get from the source that produces them in a circuit; measured in volts (V)
Term
work
Definition
application of a force to an object to move it a certain distance in the direction of the force
