Unit 3 Investigating Energy

closed (complete, working) circuit -

a closed conducting circle or loop through which current can flow

electrical energy -

a form of energy produced when electric charges flow through a conductor

light energy -

a form of energy which our eyes can detect

vibration -

a series of small, fast movements back and forth or from side to side

conductor -

a substance or object that allows energy to flow through it easily

insulator -

a substance or object that does not allow energy to flow through it easily

mechanical energy -

energy of motion

sound energy -

energy produced by vibrations

thermal energy -

energy related to the temperature of an object or a substance

open (incomplete, broken) circuit -

if the pathway is broken (burned out bulb, broken buzzer, wire cut, etc.) then electricity cannot continue to flow

energy -

the ability to cause change or do work
