Science Ch 10 Flashcards
Potential energy
energy that has the potential to do work and so the energy is ‘stored’, such 339as gravitational energy, elastic energy and chemical energy
Gravitational energy
energy stored due to the height of an object above a base level
Elastic energy
the energy made available by the flow of electric charge through a conductor
Chemical energy
potential energy derived from chemical reactions
Electrical energy
the energy made available by the flow of electric charge through a conductor
Kinetic energy
energy due to the motion of an object
Sound energy
vibrations of particles in the air
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 energy
the fraction of energy supplied to a device as useful energy. It is usually expressed as a percentage.
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
Reflected
bounced off
Transmitted
passed through something, such as light or sound passing through air
Absorbed
taken in
