1. physics the study of forces, energy, motion
2. Chemistry study of atoms and molecules, their structures, and their
interactions to form various substances.
3. Earth Science Earth's structure and composition, as well as the process-
es that change Earth, such as volcanic and seismic ac-
tivity.
4. astronomy The study of the moon, stars, and other objects in space
5. Science An organized way of gathering and analyzing evidence
about the natural world.
6. Precision a measure of how close a series of measurements are to
one another
7. SI is a scientific method of expressing the magnitudes or
quantities of important natural phenomena. There are
seven base units in the system, from which other units
are derived. Universal for comparing data.
8. physical science the sciences concerned with the study of inanimate nat-
ural objects, including physics, chemistry, astronomy, and
related subjects.
9. life science the study of living things
10. controlled exper- An experiment in which only one variable is manipulated
iment at a time. Or a condition that is being held constant
11. independent what is being changed
variable
12. dependent vari- what is being measured
able

13. control In an experiment, the standard that is used for compari-
son
14. Observational studies attempt to understand cause-and-effect relation-
experiment or ships. However, unlike experiments, the researcher is
study not able to control (1) how subjects are assigned to
groups and/or (2) which treatments each group receives.
... Therefore, a sample survey is an example of an obser-
vational study.
15. field study a research investigation carried out in a naturally occur-
ring setting
16. laboratory study Research done in a laboratory
17. Physical Model A physical representation of an object. Prototypes and
appearance models are physical models.
18. conceptual mod- a verbal or graphical explanation for how a system works
el or is organized
19. mathematical one or more equations that represent the way a system
model or process works
20. Hypothesis A testable prediction, often implied by a theory
21. Theory A hypothesis that has been tested with a significant
amount of data. Explains why something happened.
22. Law A law in science is a generalized rule to explain a body of
observations in the form of a verbal or mathematical state-
ment. Scientific laws (also known as natural laws) imply
a cause and effect between the observed elements and
must always apply under the same conditions. Explains
how it happened not why.
23. Observation Information obtained through the senses.
24. evidence proof

25. Data Facts and statistics collected together for reference or
analysis
26. Big Bang Theory Cosmological model that explains the sudden develop-
ment of the universe through expansion from a hot, dense
state.
27. plate tectonics A theory stating that the earth's surface is broken into
plates that move.
28. atomic theory a theory that states that all matter is composed of tiny
particles called atoms.
29. gram a metric unit of mass equal to one thousandth of a kilo-
gram.
30. meter The meter is the basic unit of length in the SI system
of units. ... The previous definition of the meter was one
ten-millionth of the distance from the geographic north
pole to the equator, measured over the earth's surface in
a circle running through Paris, France.
31. second SI base unit for time
32. Celsius Metric unit for measuring temperature; On this scale water
freezes at zero and boils at 100.
33. Kelvin The SI base unit of temperature
34. liter Basic unit of volume in the metric system
36. derived unit A unit defined by a combination of base units
37. direct relation- a relationship in which one variable increases with an
ship increase in another variable
, Integrated Physical Science C165 WGU Exam Test with Verified Answers
38. inverse relation- a relationship in which one variable decreases when an-
ship other variable increases
39. Speed The distance an object travels per unit of time
40. Velocity Speed in a given direction
41. Acceleration the rate at which velocity changes over time; an object
accelerates if its speed, direction, or both change
42. distance The length of a path between two points
43. Displacement Distance and direction of an object's change in position
from the starting point.
44. Balance force Equal forces acting on one object in opposite direction.
These forces then give a 0 net force, causing the object
to stay in place.
45. unequal force unbalanced forces cause a change in motion; speed.
and/or direction. When two forces act in the same direc-
tion on an object, the net force is. equal to the sum of
the two forces. When two unequal forces act in opposite
directions.
