Section 1

(26 cards)

precision

Front

a measure of how close a series of measurements are to one another (a measure of how exact a measurement is)

Back

inverse graph (this graph has a hyperbolic shape)

Front

what kind of graph is this? y = k/x

Back

SI unit prefixes

Front

the international system of units

Back

unit conversion

Front

the process of converting units of a value into another equivalent form

Back

fundamental (base) units

Front

Back

nonzero numbers, a 0 between nonzero numbers, or the final 0 after a decimal

Front

which figures are significant figures?

Back

proportional relationship

Front

a constant ratio between variables y = kx

Back

0s in front of a decimal

Front

what figures are not significant?

Back

linearization

Front

the use of known graphical relationships to derive equations

Back

unexpected results, revise hypothesis, experimentation, proven results, theory, prediction

Front

what steps do you take if you get unexpected results during an experiment?

Back

power relationship (or exponential relationship)

Front

as one variable increases, the other variable increases exponentially. this produces a curved graph y = kx^2

Back

physics

Front

the study of matter and their relationships as well as energy changes

Back

matter

Front

anything that occupies space (volume) and mass

Back

observation, question, hypothesis, experimentation, proven results, theory, prediction

Front

what are the steps of the scientific method?

Back

direct graph (this graph's shape is a straight line)

Front

what kind of graph is this? y = kx

Back

scientific model

Front

- a representation of an object or event - explains basic features of complex systems - allows scientists to test hypotheses on a realistic scale

Back

mechanics, wave phenomenon, optics, thermodynamics, electromagnetism, relativity, quantum mechanics

Front

what are the branches of physics?

Back

quadratic (or exponential) graph (this graph has a parabolic shape)

Front

what kind of graph is this? y = kx^2

Back

unit factor

Front

a mathematical term that is equivalent to 1 and used algebraically to convert units

Back

inverse relationship

Front

as one variable increases, the other variable decreases. this produces a curved graph y = k/x

Back

derived SI units

Front

2+ base units combined; - volume : cubic meter : m^3 - density : kg per cubic meter : kg/m^3 - speed : meter per second : m/s - Newton : kg m/s^2 : N - energy : Joule (kg m^2/s^2) : J - pressure : Pascal (kg/ms^2) : Pa

Back

accuracy

Front

a measure of how close a measurement is to the true value of the quantity being measured

Back

independent variable

Front

something that is changed by the scientist - what is tested - what is manipulated

Back

dependent variable

Front

something that might be affected by the change in the independent variable - what is observed - what is measured - the data collected during the investigation

Back

mechanics

Front

the study of how and why objects move

Back

uniform constant graph

Front

what kind of graph is this? x = 0
