Energy (Chapter 10) Flashcards
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
Law of Conservation of Energy
The energy made available by the flow of electric charge through a conductor
Electrical Energy
Energy stored due to the height of an object above a base level
Gravitational Potential Energy
Potential energy derived from chemical reactions
Chemical Energy
The potential energy stored in a stretched elastic material
Elastic Potential Energy
The energy stored at the centre of atoms, released from the radioactive metals uranium
Nuclear Energy
The fraction of energy supplied to a device as useful energy. It is usually expressed as a percentage
Efficiency
A material that is a poor conductor of heat
Insulators
Transfer of heat through collisions between particles
Conduction`
Transfer of heat through the flow of particles
Convection
A method of heat transfer that does not require particles to transfer heat from one place to another
Radiation
Heat transferred by radiation, as from the sun to the Earth
Radiant Heat
Bounced off
Reflected
Passed through something, such as light or sound passing through air
Transmitted
Taken in
Absorbed
Describes plants that lose their leaves during autumn and winter
Deciduous
