Suggestions for this week's quiz
(Unit 3, Quiz#2):
This week's quiz on Unit 3 material
is a scarylooking one which is tentatively scheduled for
Friday, October 30. The quiz will be a onepage quiz,
covering both sides of a single sheet of paper. The
equations for average velocity and the sine, cosine, and
tangent functions will be provided. The three 1D kinematic
equations most commonly used for projectile problems will
also be provided. You will have to "convert" them to
projectile equations in the x and y directions. Other than
a calculator, no other helps will be provided nor
allowed. Students can expect the following concepts, skills,
and problemtypes to be assessed on this quiz:
 To know the definition
of a projectile and some basic
principles characterizing the motion of a projectile
(freebody diagram, independence of v_{x} and
v_{y} components, variation of v_{x} and
v_{y} with time, values of a_{x} and
a_{y}, etc.).
 To apply one's understanding of projectiles in order
to analyze numerical information in the form of trajectory
diagrams (such as p. 22, #4 and p. 23, #7 and p.
2526) and velocityaccelerationtime
tables (such as p. 27, #8).
 To use concepts of projectile motion and the
kinematic equations in order to solve
problems involving the horizontal launching of
projectiles from an elevated position; typical
unknowns include the time of flight, the horizontal
range, the initial height and the initial launch velocity
(see the Your Turns done in class and as HW; complete
solutions on the Web).
 To be able to use SOH CAH TOA in order to resolve
a velocity vector into horizontal and vertical
components.
 To use concepts of projectile motion and the
kinematic equations in order to solve
problems involving the launching of projectiles at angles
to the horizontal; typical unknowns include the time
of flight, the horizontal range and the peak height (see
the Your Turns done in class and as HW; complete
solutions on the Web).
 To use projectile principles to explain various
realworld phenomena such as those discussed in demonstrations
and laser disc segments  the snowmobile
and the flare and the airplane
and the flare.
 An understanding of previous concepts from the first
two units. Use the links below to see the Studying
Suggestions for the three Unit 1 quizzes, the two Unit 2
quizzes, and the previous Unit 3 quiz.
Of particular
importance would be
 the relationship between acceleration
and net force,
 the relationship between acceleration,
velocity and time, and
 the independence
of free fall acceleration and mass.
