Table of Information and Equation Tables for AP Physics Examinations
The accompanying Table of Information and Equation Tables will be provided to students when
they take the AP Physics Examinations. Therefore, students may NOT bring their own copies of
these tables to the examination room, although they may use them throughout the year in their
classes in order to become familiar with their content.
Table of Information
For both the Physics B and Physics C Examinations, the Table of Information is printed near the
front cover of the multiple-choice section and on the green insert provided with the free-response
section. The tables are identical for both examinations except for one convention as noted.
For both the Physics B and Physics C Examinations, the equation tables for each examination are
printed only on the green insert provided with the free-response section. The equation tables
may be used by students when taking the free-response sections of both examinations, but NOT
when taking the multiple-choice sections.
The equations in the tables express the relationships that are encountered most frequently in
AP Physics Courses and Examinations. However, the tables do not include all equations that
might possibly be used. For example, they do not include many equations that can be derived by
combining other equations in the tables. Nor do they include equations that are simply special
cases of any that are in the tables. Students are responsible for understanding the physical
principles that underlie each equation and for knowing the conditions for which each equation is
The equation tables are grouped in sections according to the major content category in which
they appear. Within each section, the symbols used for the variables in that section are defined.
However, in some cases the same symbol is used to represent different quantities in different
tables. It should be noted that there is no uniform convention among textbooks for the symbols
used in writing equations. The equation tables follow many common conventions, but in some
cases consistency was sacrificed for the sake of clarity.
Some explanations about notation used in the equation tables:
1. The symbols used for physical constants are the same as those in the Table of
Information, and are defined in the Table of Information rather than in the right hand
columns of the tables.
2. Symbols in bold face represent vector quantities.
3. Subscripts on symbols in the equations are used to represent special cases of the
variables defined in the right hand columns.
4. The symbol
before a variable in an equation specifically indicates a change in the
variable (i.e., final value minus initial value).
5. Several different symbols (e.g. d, r, s, h,
) are used for linear dimensions such as
length. The particular symbol used in an equation is one that is commonly used for
that equation in textbooks.
