Energy Vocabulary Energy - ability of an object to do work Potential energy – ability of an object to have energy Kinetic energy – the actual movement of an object Mechanical – when potential and kinetic energy are put to an object Electric energy – form of moving energy that has a flow of electric charges Circuit- a path in which electrons move Conductor – materials that allow electrons, sound, or heat to move Insulator-materials that do not allow electrons to move, sound to travel or heat to flow Heat resistant – materials that can insulate heat Thermal energy – is determined of how active the molecules in the object are Heat-transfer of thermal energy from one substance to another and the movement of heat Current-the flow of electrons through an object Static electricity –electric energy where electrons are charged and stored Resistor – material that slows electrons Filament – a thin wire that acts as a resistor in a light bulb Series circuit – only has one path for electrons to flow, if one bulb burns out it causes the others to not burn as well Parallel circuit – contains several paths for the electrons to flow, if one burns out the others stay lit due to being on a separate path and continues to flow Open circuit – a break in the circuit where electrons can’t flow Closed Circuit- a complete connection where electrons flow continuously Electromagnet – iron bar that has wire wrapped around it that becomes a magnet when there is a current of electricity flowing though it Coil-a spiral shape Energy Vocabulary Light energy – all colors combined to produce light Reflection- when light bounces off an object Refraction- the bending of light rays Convex lens-bulging outward clear lens Concave lens-cutting inward clear lens Absorb – soaks in Transmit – passes through Opaque – a material that allows no light to pass through it Translucent -material that allows some light to pass through it Transparent – material that allows all light to pass through it Medium - an object Solar energy – the light and radiant heat from the sun Chemical energy-when energy is produced through chemical means such as the sun Transfer-to send from one place to another (thermal) Sound energy –vibration transmitted through solid, liquid, or gas Sound waves-the way sound vibrations move Vibrations-slight back and forth movements of molecules that produce sound
