, Atom - CORRECT ANSWERS-the smallest elemental unit in a sample of matter that
retains some identity. Hint: elements identify as this.
Chemistry - CORRECT ANSWERS-the study of the composition and structure of
matter, as well as the changes that occur in matter.
Atoms can be broken down into - CORRECT ANSWERS-subatomic particles (protons,
neutrons, electrons)
Molecule - CORRECT ANSWERS-a unit larger than an atom in which 2 or more atoms
are joined together.
Chemical Reaction - CORRECT ANSWERS-process which occurs when matter
undergoes a change in composition and/or structure of its molecules. Happens when 2
molecules or elements are combined, and a rearrangement occurs between atoms.
Element - CORRECT ANSWERS-A pure substance made of only one kind of atom.
Compound - CORRECT ANSWERS-Type of molecule formed by the chemical
combination of two or more different elements.
Mixture - CORRECT ANSWERS-A combination of two or more substances that are not
chemically combined
Heterogeneous Mixture - CORRECT ANSWERS-A type of mixture that varies in
composition from place to place.
Homogeneous Mixture - CORRECT ANSWERS-A mixture in which substances are
evenly distributed throughout the mixture.
projectile motion - CORRECT ANSWERS-the curved path that an object follows when
thrown, launched, or otherwise projected near the surface of Earth.
Distance - CORRECT ANSWERS-the total length of the path that the object travels.
Displacement - CORRECT ANSWERS-the length between an object's start and end-
point along with the direction it traveled.
Positive displacement travels in which directions? - CORRECT ANSWERS-North/East
Negative displacement travels in which directions? - CORRECT ANSWERS-
South/West
Distance is always positive and displacement can be positive or negative(T/F) -
CORRECT ANSWERS-T
