PHYS 1600 - EXAM 1 (KINEMATICS) | 2026 |
GUARANTEED PASS
Accuracy - Answers -the degree to which a measured value agrees with an accepted
reference value for that measurement
Base Quantity - Answers -physical quantity chosen by convention and practical
considerations such that all other physical quantities can be expressed as algebraic
combinations of them
Conversion Factor - Answers -a ratio that expresses how many of one unit are equal to
another unit
Derived Quantity - Answers -physical quantity defined using algebraic combinations of
base quantities
Derived Units - Answers -units that can be calculated using algebraic combinations of
the fundamental units
Dimensionally Consistent - Answers -equation in which every term has the same
dimensions and the arguments of any mathematical functions appearing in the equation
are dimensionless
Dimensionless - Answers -quantity with a dimension of L0M0T0I0Θ0N0J0=1; also
called quantity of dimension 1 or a pure number
Discrepancy - Answers -the difference between the measured value and a given
standard or expected value
English Units - Answers -system of measurement used in the United States; includes
units of measure such as feet, gallons, and pounds
Estimation - Answers -using prior experience and sound physical reasoning to arrive at
a rough idea of a quantity's value; sometimes called an "order-of-magnitude
approximation," a "guesstimate," a "back-of-the-envelope calculation", or a "Fermi
calculation"
Kilogram - Answers -SI unit for mass, abbreviated kg
Law - Answers -description, using concise language or a mathematical formula, of a
generalized pattern in nature supported by scientific evidence and repeated
experiments
, Meter - Answers -SI unit for length, abbreviated m
Method of Adding Percents - Answers -the percent uncertainty in a quantity calculated
by multiplication or division is the sum of the percent uncertainties in the items used to
make the calculation
Metric System - Answers -system in which values can be calculated in factors of 10
Model - Answers -representation of something often too difficult (or impossible) to
display directly
Order of Magnitude - Answers -the size of a quantity as it relates to a power of 10
Percent Uncertainty - Answers -the ratio of the uncertainty of a measurement to the
measured value, expressed as a percentage
Physical Quantity - Answers -a characteristic or property of an object that can be
measured or calculated from other measurements
Physics - Answers -the science concerned with describing the interactions of energy,
matter, space, and time; especially interested in what fundamental mechanisms
underlie every phenomenon
Precision - Answers -the degree to which repeated measurements agree with each
other
Second - Answers -the SI unit for time, abbreviated s
SI Units - Answers -the international system of units that scientists in most countries
have agreed to use; includes units such as meters, liters, and grams
Significant Figures - Answers -used to express the precision of a measuring tool used
to measure a value
Theory - Answers -testable explanation for patterns in nature supported by scientific
evidence and verified multiple times by various groups of researchers
Uncertainty - Answers -a quantitative measure of how much measured values deviate
from one another
Units - Answers -standards used for expressing and comparing measurements
Anticommutative Property - Answers -change in the order of operation introduces the
minus sign
Antiparallel Vectors - Answers -two vectors with directions that differ by 180°
