Download Energy - ability of an object to do work

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
