WGU C165 Integrated Physical Sciences correctly answered 2022Physics The study of forces, energy, motion Chemistry The study of atoms and molecules, their structures, and their interactions to form substances Earth science The study of the Earth's structure and composition, and processes that change Earth 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 variables The changing quantities in an experiment independent variable What you change in an experiment on purpose dependent variable The variable that changes because of an independent variable control variable The variable(s) you don't want to study, need to be either eliminated or kept constant observational study When systems are observed as they appear in nature, researchers do not attempt to change them physical model A model of a physical phenomenon, such as a planetary system conceptual model A model used to visualize things that cannot be seen, such as atoms mathematical model A model that treats physical objects/phenomena using mathematical methods computer model A detailed, complex model calculated by a computer principle of falsification Principle that only falsifiable statements can be subject to scientific inquiry hypothesis A testable statement about how something in nature works law A concise statement that is supported by scientific evidence and repeated experiments, describes a widespread pattern in nature (what) theory A statement that explains a wide range of observations, supported by a large body of scientific evidence (how/why) meter Base unit of length kilogram Base unit of mass second Base unit of time kelvin Base unit of temperature Derived units What is produced when the base units/quantities are combined Speed The name for the distance traveled divided by an interval of time Volume Term for the amount of space an object occupies Liquid displacement Method of determining the volume of an object by measuring the amount of liquid it displaces direct relationship A relationship between two variables where increasing one increases the other, and vice versa inverse relationship A relationship between two variables where increasing one decreases the other, and vice versa Velocity A combination of speed and direction Acceleration Term for any change in an object's speed and/or direction Force Term for a push or a pull with direction and magnitude. You may not feel it. Net force The sum of all forces acting on an object balanced forces Term for forces that combine to produce a net force of 0 Newton's first law An object in motion remains in motion unless acted on by a net force inertia The tenancy to keep the same motion/velocity or remain at rest. Newton's first law Newton's second law Net force = mass x acceleration (F = ma) Newton's third law When 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 ("For every action, an equal and opposite reaction") friction The force that opposes the motion of an object on which it acts Kinetic friction Friction between two objects moving against each other Static friction Friction between two objects touching but not moving against each other Fluid resistance Friction when an object moves through a gas or liquid Gravity Attractive force between objects directly proportional to their masses and inversely proportional to the square of their distance Linear momentum Name for the mass of an object times its velocity Law of conservation of momentum Term for the fact that momentum is conserved when two or more objects collide elasticity The amount of bounce an obj
