Test Bank for- Integrated Physical Sciences- Questions Answered Correctly (100% Pass) Physics - Answers the study of forces, energy and motion Controlled Experiment - Answers An experiment in which a scientist intentionally changes one quantity and observes how another quantity changes Variables - Answers The changing quantities in an experiment independent variable - Answers the variable that is changed by the experimenter in the an experiment Dependant variable - Answers the variable that changes because of the independent variable Control Variable - Answers The variable that scientists do not wish to study that needs to be either eliminated or kept constant Observational Studies - Answers Experiments in which systems are observed as they appear in nature, and researchers do not attempt to change them field studies - Answers observational studies done outside a laboratory setting laboratory studies - Answers experiments that take place in a highly controlled, artificial setting physical model - Answers a model that represents a real object or a phenomenon, usually on a smaller scale conceptual model - Answers a model that can be used to visualize things that cannot be seen, such as atoms mathematical model - Answers a model that describes physical objects or phenomena using mathematical methods computer model - Answers 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 - Answers a mathematical relationship between two variables whose ratio remains constant as their numerical values change (synonymous with positive correlation) inverse proportionality - Answers a mathematical relationship between variables in which an increase in the value of one causes a decreased in the value of the other no correlation - Answers a lack of relationship between variables on a graph; a change in one value does not affect the other proportionality constant - Answers a parameter that quantifies the relative changes in variables that are directly or inversely proportional origin of the plot - Answers the point on a graph where the value of both x and y axes are zero scatterplot - Answers a type of graph comparing two variables as data points in cartesain, x-y coordinates ratio - Answers a quantity that compares the values of two variables What describes length? - Answers a distance between two points what describes mass? - Answers amount of matter in an object SI unit of length - Answers meter (m) SI unit of mass - Answers kilogram (kg) SI unit of time - Answers second (s) SI unit of temperature - Answers Kelvin (K) which symbol stands for milli-? - Answers m which symbol stands for micro-? - Answers μ which symbol stands for nano-? - Answers n which symbol stands for mega-? - Answers M Which symbol stands for kilo-? - Answers k Which symbol stands for centi-? - Answers c density - Answers depends on the material itself, not on the object's size or mass molar mass - Answers a derived unit specifying the number of a particular particle or molecule in one liter of another substance speed - Answers defined as the distance traveled per time interval volume - Answers the amount of space an object occupies velocity - Answers the objects speed and direction acceleration - Answers a rate at which the velocity of an object changes with respect to time force - Answers a push or a pull balanced forces - Answers forces that combine to produce a net force of zero zero net force - Answers there is no net force and therefore no acceleration
