/.variables - Answer-The changing quantities in an experiment
/.independent variable - Answer-What you change in an experiment on purpose
/.dependent variable - Answer-The variable that changes because of an independent
variable
/.control variable - Answer-The variable(s) you don't want to study, need to be either
eliminated or kept constant
/.observational study - Answer-When systems are observed as they appear in nature,
researchers do not attempt to change them
/.physical model - Answer-A model of a physical phenomenon, such as a planetary
system
/.conceptual model - Answer-A model used to visualize things that cannot be seen, such
as atoms
/.mathematical model - Answer-A model that treats physical objects/phenomena using
mathematical methods
/.computer model - Answer-A detailed, complex model calculated by a computer
/.principle of falsification - Answer-Principle that only falsifiable statements can be
subject to scientific inquiry
, /.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, describes a widespread pattern in nature (what)
/.theory - Answer-A statement that explains a wide range of observations, supported by
a large body of scientific evidence (how/why)
/.meter - Answer-Base unit of length

/.Speed - Answer-The name for the distance traveled divided by an interval of time
/.Volume - Answer-Term for the amount of space an object occupies
/.Liquid displacement - Answer-Method of determining the volume of an object by
measuring the amount of liquid it displaces
/.direct relationship - Answer-A relationship between two variables where increasing one
increases the other, and vice versa
/.inverse relationship - Answer-A relationship between two variables where increasing
one decreases the other, and vice versa
/.Velocity - Answer-A combination of speed and direction
/.Acceleration - Answer-Term for any change in an object's speed and/or direction
/.Force - Answer-Term for a push or a pull with direction and magnitude. You may not
feel it.
/.Net force - Answer-The sum of all forces acting on an object
/.balanced forces - Answer-Term for forces that combine to produce a net force of 0
/.Newton's first law - Answer-An object in motion remains in motion unless acted on by a
net force
