ke and pe energy
what type of energy deals with moving objects and motion
kinetic energy!
what is a planetary nebula?
A ring-shaped nebula formed by an expanding shell of gas around a old star.
what energy causes pollution and habitat damage
nonrenewable
this is what is horizontal on the periodic table
periods
the number of electrons are shared
the faster an object moves it gains more of this energy
kinetic
mass
this energy turns organic material into energy
biomass energy
the number of protons in the atom are found by what number on the atom
the atomic number
this happens in an ionic bond
electrons are transferred
this energy is stored
potential energy
what is it called when a star is starting to form but does not go under nuclear fusion yet
protostar
true or false? renewable energy is always reliable in every situation
false!
this shows you how many valence electrons something has
group number 1-8
all atoms want to get to this number of electrons
8!
gravitational potential energy depend on what two things
height and mass of the obect
when a star begins fusion what do the two hydrogen atoms fuse into
helium
what energy can be used faster than it is able to be replenished
nonrenewable energy
these are vertical lines on the periodic table
groups
in a covalent bond these to catagories on the periodic table bond
metal and non metal
how much kinetic energy does a bike moving at 22 m/s that weighs 47 kgs
24299 joules of kinetic energy
what happens to a supergiant star after it dies
it explodes into supernova
true or false? all of nonrenewable energies cause no habitat disruption or pollution
false!
the number of nuetrons is found by this number minus the number of protons
the atomic mass
this happens in an ionic bond
electrons are transferred
