WGU C165 Integrated Physical Sciences Vocabulary
1. Physics: The study of forces, energy, motion
2. Chemistry: The study of atoms and molecules, their structures, and their
inter- actions to form substances
3. Earth science: The study of the Earth's structure and composition, and
processes that change Earth
4. essential attributes of science: Studies the natural
world Uses testable ideas
Relies on data from
observations/experiments Presented for
evaluation by other scientists Leads to further
questions/research
5. variables: The changing quantities in an experiment
6. independent variable: What you change in an experiment on purpose
7. dependent variable: The variable that changes because of an
independent variable
8. control variable: The variable(s) you don't want to study, need to be
either eliminated or kept constant
9. observational study: When systems are observed as they appear in
nature, researchers do not attempt to change them

combined

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