Energy Flashcards
The ability to cause change
Energy
Stored energy due to the interaction between objects and particles
Potential energy
The energy stored in and released from the bonds of atoms
Chemical energy
The energy stored and released from the nucleus of an atom
Nuclear energy
Energy due to motion
Kinetic energy
The energy in an electric current
Electric energy
A collection of parts that interact and act together as a whole
System
The sum of pontenial and kinetic energy in a system
Mechanical energy
The sum of kinetic and potential energy of the particles that make up an object
Thermal energy
A disturbance that transfers energy to one place form another
Wave
Energy carried by sound waves
Sound energy
Moves form an electric signal that travels to your brain
How sound travels from a voice to your ear
A form of energy carried by electromagnetic waves
Light
A from of energy carried by electromagnetic waves
Radiant energy
The distance from one point on a wave to the nearest point
Wavelength
Energy transferred from one form to another, but can’t be created or destroyed
The laws of conservation of energy
When energy moves from one object to the other without changing form
Energy transfer
When one form of energy is converted to another form of energy
Energy transformation
The transfer of energy that occurs when force makes an object move
Work
A system that exchanges matter or energy with the environment
Open system
A system that does not exchanges matter or energy with the environment
Closed system
An energy resource that is replaced fast as or as fast that it is used
Renewal energy resource
Solar Wind Hydroelectric Geothermal Biomass
5 renewable energy sources
An energy resource that is available in limited amounts
Nonrenewable energy resources
The measure of average kinetic energy of particles in a material
Temperature
Kelvin (K) and Celsius (C)
What scientists use
The increase in volume of a material due to a temp increase
Thermal expansion
When the temp of a material decreases the volume decreases
Thermal contraction
The movement thermal energy from a region of high temp
Heat
When temps of material are in contact are the same
Thermal equilibrium
Is the change of state from liquid to gas
Vaporization
The change of state that occurs when a solid changes to a gas
Sublimation
The change from a gas to a solid
Deposition
A material in which thermal energy moves quickly
Thermal conductor
A material in which thermal energy moves slowly
Thermal insulator
