Chapter 15 Energy Flashcards
the ability to cause a change in matter
energy
a law that states that energy can never be made or destroyed, but it can change forms
law of conservation of energy
the energy of motion
kinetic energy
the energy an object has because of its condition or position
potential energy
the movement of energy from one place or object to another
energy transfer
of the sun
solar
energy that comes from the sun
solar energy
_____ is radiation we see, and heat is radiation we feel
light
stored energy; energy stored in fuel
chemical energy
the combination of all the potential and kinetic energy that something has
mechanical energy
energy that comes from an electric current
electric energy
energy in the form of vibrations that travel through matter
sound
the transfer of thermal energy between objects with different temperatures
heat
the average kinetic energy of all particles in a substance
temperature
a set of parts acting together as a whole object
system
the transfer of thermal energy from one object directly into another
conduction
the transfer of thermal energy through the movement of a gas or a liquid
convection
the transfer of energy by waves that move through matter and space
radiation
__________ occurs when heat or light bounces off an object.
reflection
anything that slows the movement of thermal energy
insulator
anything that allows thermal energy to move through easily
conductor
electricity made by the energy of falling water
hydroelectric energy
the remains or traces of past life found in sedimentary rocks
fossil
fuel that formed from the remains of once-living things
