INTRODUCTION
Conceptual Questions
1. Knowledge of physics is important for a full understanding of many scientific disciplines, such as chemistry,
biology, and geology. Furthermore, much of our current technology can only be understood with knowledge of
the underlying laws of physics. In the search for more efficient and environmentally safe sources of energy, for
example, physics is essential. Also, many people study physics for the sense of fulfillment that comes with
learning about the world we inhabit.
2. Without precise definitions of words for scientific use, unambiguous communication of findings and ideas
would be impossible.
3. Even when simplified models do not exactly match real conditions, they can still provide insight into the
features of a physical system. Often a problem would become too complicated if one attempted to match the
real conditions exactly, and an approximation can yield a result that is close enough to the exact one to still be
useful.
4. After solving a problem, it is a good idea to check that the solution is reasonable and makes intuitive sense. Do
the units work out correctly? In the symbolic version of the answer, before numbers are substituted, would the
expression change in a reasonable way if each parameter were made larger? Smaller? Very much larger or
smaller? It may also be useful to explore other possible methods of solution as a check on the validity of the
first. A good student thinks of a framework of ideas and skills that they are constructing for themself. The
problem solution may extend or strengthen this framework
5. Scientific notation eliminates the need to write many zeros in very large or small numbers, and to count them.
Also, the number of significant digits is indicated unambiguously when a quantity is written this way.
6. In scientific notation the decimal point is often placed after the first (leftmost) numeral. The number of digits
written equals the number of significant figures.
7. Not all of the significant digits are known definitely. The last (rightmost) digit, called the least significant digit,
is an estimate and is less definitely known than the others.
8. It is important to write a quantity with the correct number of significant figures so that we can indicate how
precisely a quantity is known and so that we do not mislead the reader by writing digits that are not at all known
to be correct.
9. The kilogram, meter, and second are three of the base units used in SI, the international system of units.
10. The international system SI uses a well-defined set of internationally agreed upon standard units and makes
measurements in terms of these units, their combinations, and their powers of ten. The U.S. customary system
contains units that are primarily of historical origin and are not based upon powers of ten. As a result of this
international acceptance and of the ease of manipulation that comes from dealing with powers of ten, scientists
around the world prefer to use SI.
11. Fathoms, kilometers, miles, and inches are units with the dimension length. Grams and kilograms are units with
the dimension mass. Years, months, and seconds are units with the dimension time.
, Chapter 1: Introduction 2
12. The first step toward successfully solving almost any physics problem is to thoroughly read the question and
obtain a precise understanding of the scenario. The second step is to visualize the problem, often making a quick
sketch to outline the details of the situation and the known parameters.
13. Trends in a set of data are often the most interesting aspect of the outcome of an experiment. Such trends are
more apparent when data is plotted graphically rather than listed in numerical tables.
14. The statement gives a number for the speed of sound in air, but fails to indicate the units used for the
measurement. Without units, the reader cannot relate the speed to one given in familiar units such as km/s.
