NAVY NAPT STUDY GUIDE
Atom - ANSWERS-the smallest elemental unit in a sample of matter
that retains some identity. Hint: elements identify as this.
Chemistry - 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 - ANSWERS-subatomic particles
(protons, neutrons, electrons)
Molecule - ANSWERS-a unit larger than an atom in which 2 or more
atoms are joined together.
Chemical Reaction - 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 - ANSWERS-A pure substance made of only one kind of
atom.
Compound - ANSWERS-Type of molecule formed by the chemical
combination of two or more different elements.
,Mixture - ANSWERS-A combination of two or more substances that
are not chemically combined
Heterogeneous Mixture - ANSWERS-A type of mixture that varies in
composition from place to place.
Homogeneous Mixture - ANSWERS-A mixture in which substances
are evenly distributed throughout the mixture.
projectile motion - ANSWERS-the curved path that an object follows
when thrown, launched, or otherwise projected near the surface of
Earth.
Distance - ANSWERS-the total length of the path that the object
travels.
Displacement - ANSWERS-the length between an object's start and
end-point along with the direction it traveled.
Positive displacement travels in which directions? - ANSWERS-
North/East
Negative displacement travels in which directions? - ANSWERS-
South/West
, Distance is always positive and displacement can be positive or
negative(T/F) - ANSWERS-T
Displacement is always positive and distance can be positive or
negative(T/F) - ANSWERS-F
Speed - ANSWERS-the rate at which someone or something is able to
move or operate.
formula for distance - ANSWERS-d=vt; distance= speed * time
formula for displacement - ANSWERS-d=vt; displacement= velocity
* time
distance and displacement share the same formula(T/F) - ANSWERS-
T
Is speed scalar or vector? - ANSWERS-scalar
Is velocity scalar or vector? - ANSWERS-vector
Speed is always positive(T/F) - ANSWERS-T
Speed is always negative(T/F) - ANSWERS-F
