Flashcards in Energy Deck (30):
Energy that has the potential to do work.
Energy that is quickly transformed into movement.
relating to the nucleus of an atom.
the motion of large objects
relating to heat.
an act of moving.
a distinct compound or substance, especially one which has been artificially prepared or purified.
of, worked by, charged with, or producing electricity.
the natural agent that stimulates sight and makes things visible.
vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.
relating to movement towards a centre of gravity.
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.
used to move charged particles through a wire from a power plant to our homes and businesses. The movement of a charged particle through a wire is called current, or more commonly, electricity.
Gravitational Potential Energy
energy an object possesses because of its position in a gravitational field.
Elastic Potential Energy
Elastic potential energy is Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched.
a measure of how much work or energy is conserved in a process.
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
-the process by which sound waves travel through a
-the transmission of impulses along nerves.
The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
the degree of compactness of a substance.
Describes plants that lose their leaves during autumn and winter
A Material that is a Poor Conductor of heat.
Heat transferred from the Sun to the Earth.
Passing through something such as Light or Sound passing through the air.
Something that releases its own light.
Describes objects that emit light when they are hot.
Describes light sent in many directions.
