NAVY NAPT STUDY GUIDE QUESTIONS AND
ANSWERS 2025
Atom - .....ANSWER... ✔✔ the smallest elemental unit
in a sample of matter that retains some identity. Hint:
elements identify as this.
Chemistry - .....ANSWER... ✔✔ the study of the
composition and structure of matter, as well as the
changes that occur in matter.
Atoms can be broken down into - .....ANSWER... ✔✔
subatomic particles (protons, neutrons, electrons)
Molecule - .....ANSWER... ✔✔ a unit larger than an
atom in which 2 or more atoms are joined together.
Chemical Reaction - .....ANSWER... ✔✔ 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 - .....ANSWER... ✔✔ A pure substance made
of only one kind of atom.
Compound - .....ANSWER... ✔✔ Type of molecule
formed by the chemical combination of two or more
different elements.
Mixture - .....ANSWER... ✔✔ A combination of two or
more substances that are not chemically combined
Heterogeneous Mixture - .....ANSWER... ✔✔ A type
of mixture that varies in composition from place to
place.
Homogeneous Mixture - .....ANSWER... ✔✔ A mixture
in which substances are evenly distributed throughout the
mixture.
projectile motion - .....ANSWER... ✔✔ the curved path
that an object follows when thrown, launched, or
otherwise projected near the surface of Earth.

Distance - .....ANSWER... ✔✔ the total length of the
path that the object travels.
Displacement - .....ANSWER... ✔✔ the length between
an object's start and end-point along with the direction it
traveled.
Positive displacement travels in which directions? -
.....ANSWER... ✔✔ North/East
Negative displacement travels in which directions? -
.....ANSWER... ✔✔ South/West
Distance is always positive and displacement can be
positive or negative(T/F) - .....ANSWER... ✔✔ T
Displacement is always positive and distance can be
positive or negative(T/F) - .....ANSWER... ✔✔ F
Speed - .....ANSWER... ✔✔ the rate at which
someone or something is able to move or operate.
, 4|Page
formula for distance - .....ANSWER... ✔✔ d=vt;
distance= speed * time
formula for displacement - .....ANSWER... ✔✔ d=vt;
displacement= velocity * time
