1[blank_start]Physics[blank_end] is the study of matter and energy and their relationships
- APhysics
2[blank_start]Dimensional analysis[blank_end] is used to check that an answer will be in the correct units.
- ADimensional analysis
3The result of any mathematical operation with measurements never can be
more precise than the [blank_start]least-precise[blank_end] measurement involved in the operation- Aleast-precise
4The scientific method is a systematic method of [blank_start]observ[blank_end]ing, [blank_start]experiment[blank_end]ing, and [blank_start]analyz[blank_end]ing to answer questions about the natural world
- Aobserv
- Bexperiment
- Canalyz
5Scientific ideas [blank_start]change[blank_end] in response to new data
- Achange
6New scientific findings must be [blank_start]reproducible[blank_end]; that is, others must be able to [blank_start]measure[blank_end] and find the same [blank_start]results[blank_end]
- Areproducible
- Bmeasure
- Cresults
7All measurements are subject to some [blank_start]uncertainty[blank_end]
- Auncertainty
8[blank_start]Precision[blank_end] is the degree of exactness with which a quantity is measured. Scientific notation shows how [blank_start]precise[blank_end] a measurement is
- APrecision
- Bprecise
9[blank_start]Accuracy[blank_end] is the extent to which a measurement matches the true value.
- AAccuracy
10Data are plotted in [blank_start]graphical[blank_end] form to show the relationship between two variables
- Agraphical
11The line that best passes through or near graphed data is called the [blank_start]line of best fit[blank_end]. It is used to describe the data and to predict where [blank_start]new data[blank_end] would lie on the graph.
- Aline of best fit
- Bnew data
12A graph in which data points lie on a straight line is a graph of a [blank_start]linear[blank_end] relationship.
- Alinear
13The equation for a linear relationship is [blank_start]y=mx+b[blank_end]. In the general equations, m and b are [blank_start]constants[blank_end].
- Aconstants
- By=mx+b
14The slope of a straight-line graph is the [blank_start]vertical[blank_end] change ([blank_start]rise[blank_end]) divided by the [blank_start]horizontal[blank_end] change ([blank_start]run[blank_end]) and often has a physical meaning
- Arise
- Brun
- Cvertical
- Dhorizontal
15The equation for slope is [blank_start]m[blank_end] = [blank_start]rise[blank_end]/[blank_start]run[blank_end].
- Am
- Brise
- Crun
16The graph of a quadratic relationship is a parabolic curve. It is represented by the equation [blank_start]y[blank_end] = [blank_start]ax[blank_end]^2 + [blank_start]bx[blank_end] + [blank_start]c[blank_end]. The constants a, b, and c can be found with a computer or a graphing calculator; simpler ones can be found using algebra
- Ay
- Bax
- Cbx
- Dc
17The graph of an inverse relationship between x and y is a [blank_start]hyperbolic[blank_end] curve. It is represented by the equation y=[blank_start]a[blank_end]/[blank_start]x[blank_end], where a is a constant
- Aa
- Bx
- Chyperbolic
