```					                  Semester Review Sheet for Fall 2003 Semester
AP Physics - Dr. Clark

Topic Outline:
I. Introduction to physics - Chapter 1
A. Dimensions and units
B. Signiﬁcant digits
1. Addition/Subtraction - round to the ﬁrst uncertain place (moving from left
to right)
2. Multiplication/Division - round to as many signiﬁcant digits as the number
with the least number of digits
C. Types of Errors
1. Random - repeated measurements ﬂuctuating around the true value (Ex:
the parallax of viewing a meter stick)
2. Systematic - repeated measurements being oﬀ by the same amount each
time (Ex: the meter stick is missing the increment between 39 cm and 40
cm because of a blunder in its manufacture)
3. Other error types (blunders, counting errors, etc.) fall into the two broad
categories of random and systematic, depending on how they aﬀect the
measurement
4. Many speciﬁc error sources have both random and systematic
characteristics (Ex: the drunk stepping oﬀ the crop circle radius)

Exam Format: The format of the exam will be the same as the tests during the
semester and the same as the actual AP exam. There will be a multiple choice
section and a “free response” section (problems). You will not be able to use your
calculator or formula sheet on the multiple choice section. Like we have done on
previous tests, you will work the multiple choice section ﬁrst. After you turn in that
portion, I will give you the formula sheet and you may get out your calculator.
Suggested Strategy:
1. Know how to work all the tests and understand the physics principles
involved (if you just memorize the solutions to the tests you probably won’t
do very well on the physics exam).
2. Know how to work all the homework assignments for the semester (again,
you need to understand the problems, not just memorize).
3. Study the lecture notes.
4. Read and study the textbook.
If you have time to master all 4 of the above categories, congratulations! You should
do very well on the exam. However, since the time that you will ﬁnd available to
you for preparing for the exam is ﬁnite, you will probably not have time to do all of
the above (for example, read 14 chapters in the text). I have listed these categories
in order of decreasing priority. For instance, knowing and understanding the tests is
the most important task. After you’ve mastered the old tests (including the practice
ones), homework, and notes, then you should read the textbook. Of course, this
doesn’t mean that you should focus exclusively on the tests without
looking at the other study sources until you understand every aspect of
every test. You should look at notes, homework, and the book to help
you understand any part of the tests that you don’t remember. If this
suggested strategy is not clear to you, please talk with me individually!
Problem Types:
1. Dimensional analysis and converting from one set of units to another (such as
m/sec to mi/hr).
2. Interpreting graphs and calculating quantities from graphs, such as speed and
acceleration (both average and instantaneous).
3. Constantly accelerated motion in one dimension (such as masses moving up
or down ramps, balls thrown straight up, cars accelerating uniformly along
level roads, elevators, etc.)
4. Adding vectors mathematically.
5. Two dimensional trajectory problems (cars jumping gorges, etc.).
6. Newton’s laws of motion (frictional forces, net force acting on objects
undergoing constant acceleration).
7. Diﬀerence between mass and weight.
8. Apparent weight in diﬀerent reference frames (like an elevator).

4
9. Forces (such as gravity, normal force, friction, applied forces) acting on
objects sliding up or down inclined planes.
10. Work done by forces.
11. Potential (both elastic and gravitational) and translational kinetic energy of
objects.
12. Energy transformations, such as problems involving the work-kinetic energy
theorem, conservation of mechanical energy, work done by friction.
13. Power (rate of work or energy delivery).
14. Impulse and momentum.
15. Conservation of linear momentum in one and two dimensions. Objects stick
together, objects ricochet, object explodes. Calculate whether or not KE is
conserved.
16. Rotational motion: angular displacement, angular speed, angular
acceleration.
17. Relationship between angular and linear quantities.
18. Centripetal acceleration and centripetal force.
19. Mutual force of gravitational attraction between masses.
20. Torque produced by forces.
21. Objects in equilibrium, both translational and rotational (apply the three
equilibrium conditions).
22. Buoyant forces acting on an object immersed in a ﬂuid (Archimedes’
principle).
23. Hydralic lift.
24. Variation of pressure with depth.
25. Lift pump and soda straw. Maximum height that a lift pump can lift a
certain liquid.
26. Fluid ﬂow (continuity equation and Bernoulli’s equation).
27. Expansion and contraction of solids as a function of temperature.
28. Gas laws.
29. Mechanical equivalent of heat (for example, dropping a penny and calculating
how much it heats up).
30. Speciﬁc heat and calorimetry.
31. Latent heat of fusion and vaporization.
32. Work done by a gas. Extracting or calculating information from a PV
diagram.
33. Eﬃciency of heat engines, both actual and theoretical maximum (Carnot
eﬃciency).
34. Hooke’s law.

5
35. Elastic potential energy.
36. Simple harmonic motion: position, velocity, acceleration, amplitude, etc.
37. Period of a pendulum.
38. Wave motion (frequency, amplitude, speed and wavelength).
39. Speed of waves on a string.
40. Superpositon of waves.
41. Standing waves on a string.
42. Standing waves in an air column.
43. Beats.
Of course, combining problem types is a strong possibility.
