energy
Energy can be transferred from one form into another or one region into another but energy cannot be created or destroyed
law of conservation of energy
the smallest unit of matter
atom
the movement of thermal energy from a warmer object to a cooler object
heat
the remains of ancient organisms that can be burned as an energy source
fossil fuels
the material involved is structurally the same before and after the change
physical change
energy due to motion
kinetic energy
a substances that consists of just one type of atom
element
the transfer of thermal energy between materials by the collision of particles
conduction
a device that regulates the temperature of a system
thermostat
this determines an objects kinetic energy
mass and speed
stored energy due to the interactions between objects or particles
potential energy
the 5 parts of an atom
nucleus, neutrons, protons, electrons, and electron orbit
the transfer of thermal energy by the movement of particles from one part of a material to another
convection
the breaking or forming of bonds between molecules or atoms, making at least one new substance
chemical change
this determines an object's potential energy
mass and height
an energy resource that is available in limited amounts or that is used faster than it is replaced in nature
nonrenewable energy
the 3 parts of an element
element name, element symbol, atomic number
the amount of energy required to increase the temperature of one kilogram of a material by one degree celsius
specific heat
anything that has mass and takes up space
matter
this helps a bike stop when you put on the brakes
friction
an energy resource that is replaced as fast or faster than it is used
renewable energy
an example of an element
aluminum
the transfer of energy from one material to another by electromagnetic waves
radiation
represents the amount of matter in a particle or object
mass
this is the transfer of energy that occurs when a force is applied over a distance
