energy is the ability to do ________ or cause ____________
work, change
______________ energy- energy of motion
kinetic
any object that is ___________ has kinetic energy
moving
examples of kinetic energy
walking music/sound, sun etc.
______________ energy - stored energy or energy of position
potential
potential energy is -________ and ready to be used
stored
examples of potential energy
pulled rubber band, holding an object high above the ground
what is gravitational energy?
the energy an object has because of how high off the ground is. so therefore, the higher an object is off the ground, the more gravitational energy it has.
example of gravitational energy
a ball being thrown up in the air
what is elastic energy?
the energy that is stored in an object when that object is temporarily forced out of its normal shape. this energy is only stored when the object is being stretched, and released when compressed again.
example of elastic energy
rubber band, spring
what is chemical energy?
the energy that is stored in the tiny bonds that hold atoms and molecules together.
what is nuclear energy?
the energy that is stored inside the center of an atom.
what is mechanical energy?
the energy that involves anything with motion.
what is thermal energy?
the energy involving heat
what is radiant energy?
the energy involving light.
what is sound energy?
the energy that uses vibrations

kinetic energy
energy can __________ from one form to another
transfer
energy cannot be _________ or __________
created, destroyed
energy can only be ___________ or ___________
stored, transfered
the ___________ amount of energy stays the same
total
When you turn off a light, the energy doesn’t disappear. Instead, it…
is stored
mass
how heavy an object is
the more mass…
the more kinetic energy

how fast the object is moving
the more speed…
the more kinetic energy
how to find velocity
divide the distance by the time
