energy Flashcards
potential energy
Energy that has the potential to do work and so the energy is ‘stored’
kinetic energy
Energy due to the motion of an object
conduction
transfer of heat through collisions between particles
convection
transfer of heat through the flow of particles
radiation
a method of heat transfer that does not require particles to transfer heat from one place to another
radiant heat
heat transferred by radiation, as from the sun to the Earth
reflected
bounced off
transmitted
passed through something, such as light or sound passing through air
sound
energy carried by air in the room
heat
energy that causes objects to gain temperature
light
energy that may be released
electrical
energy supplied to homes by power lines
nuclear
energy stored in the nucleus of atoms that can release energy slowly
chemical
energy stored in chemicals that, when reacted together such as in burning reactions, release heat, sound light
elastic
energy stored by an elastic object that is stretched
gravitational
potential energy on an object elevated above the ground
mechanical
the energy associated with the movement and position of things
Law of Conservation of Energy
a law that states that energy cannot be made or lost. However, energy can be transformed from one type to another or transferred from one object to another.
efficiency
q
density
it is how much energy is stored in a given system
deciduous
describes plants that lose their leaves during autumn and winter
conductor
poor insulator, it is also an object that transmits heat or electricity
insulator
poor conductor, are those that contain air that is restricted from moving. they also restrict heat loss from both conduction and convection.
luminous
it is releasing its own light
