Matter
Anything that takes up space and has mass.
What is matter?
the ability to do work
What is energy?
a type of energy caused by the vibrations of air molecules
What is sound?
atoms and molecules
what is matter made of?
kinetic, potential, and sound are examples of
what is energy?
the amount of matter an object has
what is mass?
energy waiting to be used and turned into kinetic energy; stored energy
what is potential energy?
the back and forth motion of molecules (bunches of atoms)
what are vibrations?
What is true?
jumping, skipping, running, walking, talking, writing
what are examples of kinetic energy?
bunches of atoms that make up objects
What are molecules?
the energy of matter in motion
what is kinetic energy?
vibrations travel through the air in waves; can also travel through solids or liquids!
what is how does sound travel to/reach our ears?
oxygen and hydrogen atoms make up this molecule
what is a water molecule?
A rock about to fall off of a cliff
what is potential energy?
an atom
What is the building block of ALL matter?
when an object is in motion
what is how do we know when an object has kinetic energy?
______ is how high or low a sound is while _____ is how loud or soft a sound is
what are pitch and volume?
mass is the amount of matter something has while this is the force acting on an object due to gravity (helps us not float into space)
what is weight?
the rate at which an object moves
what is speed?
solids, liquids, and gases
What are the three states of matter?
energy makes matter move
what is the connection between energy and matter?
what is the cochlea?
this is the amount of matter something has while this is the force that helps us not float into space; one changes in space while the other remains the same
what are mass and weight?
the more speed an object has, the more kinetic energy it has. the less speed an object has, the less kinetic energy it has.
what is the connection between speed and energy?
