BANK QUESTIONS AND CORRECT DETAILED ANSWERS|ALREADY GRADED A+
Controlled Experiment - (ANSWER)an experiment in which a scientist intentionally changes
one quantity and observes how another quantity changes
Variables - (ANSWER)the changing quantities in an experiment
Independent Variable - (ANSWER)the variable that is changed by the experimenter in an @#$%^
experiment &*()(*&
^%$
Dependent Variable - (ANSWER)the variable that changes because of the independent
variable
Control Variable - (ANSWER)the variable that scientists do not wish to study that needs to
either be eliminated or kept constant
Observational Studies - (ANSWER)experiments in which systems are observed as they
appear in nature, and researchers do not attempt to change them
Field Studies - (ANSWER)observational studies done outside a laboratory setting
Laboratory Studies - (ANSWER)experiments that take place in a highly controlled, artificial
setting
Physical Model - (ANSWER)a model that represents a real object or a phenomenon, usually
on a smaller scale
Conceptual Model - (ANSWER)a model that can be used to visualize things that cannot be
seen, such as atoms
Mathematical Model - (ANSWER)a model that describes physical objects or phenomena
using mathematical methods
Computer Model - (ANSWER)a model that uses computers to explain and predict complex
systems, such as weather patterns and the detailed movements of objects in the solar
system
Direct Proportionality - (ANSWER)a mathematical relationship between two variables
whose ratio remains constant as their numerical values change (synonymous with positive
correlation)
Inverse Proportionality - (ANSWER)a mathematical relationship between variables in which
an increase in the value of one causes a decrease in the value of the other (synonymous
with negative correlation)
No Correlation - (ANSWER)a lack of relationship between variables on a graph; a change in
one value does not affect the other

Proportionally Constant - (ANSWER)a parameter that quantifies the relative changes in
variables that are directly or inversely proportional
Density - (ANSWER)depends on the material itself, not on the object's size or mass
Molar Mass - (ANSWER)a derived unit specifying the number of grams of a substance per @#$%^
mole of that substance &*()(*&
^%$
Molar Units - (ANSWER)the number of moles of a particular particle or molecule in one liter
of another substance
Velocity - (ANSWER)an object's speed and direction
Acceleration - (ANSWER)rate at which the velocity of an object changes with respect to
time
Hypothesis - (ANSWER)a testable statement about how something in nature works
Law - (ANSWER)a concise statement that is supported by scientific evidence and repeated
experiments and describes a widespread pattern in nature
Theory - (ANSWER)a statement that explains a wide range of observations and that is
supported by a large body of scientific evidence
Newtons First Law - (ANSWER)the net force on an object is the cause of its acceleration
Intertia - (ANSWER)the tendency to keep the same motion, to remain at rest, or to maintain
the same velocity
Newtons Second Law - (ANSWER)the acceleration of an object depends on the mass of the
object and the amount of force applied
Netwons Third Law - (ANSWER)whenever one object exerts a force on a second object, the
second object exerts a force of the same magnitude in the opposite direction on the first
object
Friction - (ANSWER)the force that opposes the motion of an object on which it acts
Linear Momentum - (ANSWER)the mass of an object times its velocity
Law of conservation of momentum - (ANSWER)a scientific law that states that momentum
is conserved when two or more objects collide
Work - (ANSWER)energy that is being used or converted; results in the displacement of an
object in the direction of an applied force
