Suggestions for this week's quiz
(Unit 2, Quiz#2):
This week's quiz on Unit 2 material
is tentatively scheduled for Friday, October 8. The
quiz will be a onepage quiz, covering both sides of a
single sheet of paper. The quiz will be much like last
week's quiz, except that there will be more word problems
and a heavier emphasis on the force of friction and
freefall acceleration. The equations for net force,
frictional force, gravitational force, and average
acceleration will be provided; the value of g will be given;
the kinemiatic equations will be given. 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:
 An understanding of inertia
and its relation to mass and various applications of
this concept (as discussed in class and in the Hewitt
book).
 An understanding of Newton's
first law of motion and its application to a variety
of motion phenomena and a
recognition of the various misconceptions which are
contrary to Newtonian thinking. Be certain that you
believe that an object can move to the right without
having to have a force to the right.
 An understanding of the
distinction between mass and weight and an ability to
determine one quantity if given the other. This is a sure
bet.
 An understanding of what a force is and of the
actionreaction nature of all forces.
 An ability to recognize
the presence or absence of forces in any physical
situation and to draw
a freebody diagram (illustrating the presence, the
type, and the direction of all forces acting upon an
object) if given a verbal description of a physical
situation. You can be certain of having to draw 24
FBDs.
 An understanding of Newton's
second law of motion and its use to make quantitative
predictions of the effect of one variable upon another
variable (e.g., the effect of the doubling of the
mass upon the acceleration). If the mass is doubled and
the net force is tripled, then the acceleration is
...
 A solid grasp of the relationships between mass,
acceleration, net force, and individual force values and
the application of this understanding to determining the
numerical values of such quantities. See Finding
Invidual Force Values or Finding
Acceleration.
 An ability to use Newton's second law and a force
analysis to solve word problems involving forces and
motion (much like the last question on last week's quiz
and like the halfpage sheet we did in class). See
Finding
Invidual Force Values or Finding
Acceleration.
 An understanding of the
forcemassacceleration relationships for freefall
motion and an ability to use kinematic equations to
predict the final motion parameters of a freefalling
object (as on pp. 2930 of the packet).
 An understanding of air
resistance and terminal velocity and the ability to
solve word problems involving air resistance and terminal
velocity. (Review the Bronco Brown handout and view the
Bronco Brown
animation.)
 An understanding of previous concepts from previous
units  especially dot diagrams, velocitytime graphs,
and vt numerical data. Use the links below to see the
Studying Suggestions for the first four quizzes of the
year.
Beware of Those
Misconceptions

This quiz will target specific student
misconceptions associated with force and motion. In
addition to usage of module
3 ("Newton's Laws") and module 4 (F = m*a) of Minds
On Physics, students should also give attention
to the content of two web pages which complement
class discussion. The two pages relate to:

There are several sample quizzes for this unit. Some of
the questions found on the first quizzes of the unit are
representative of the questions often found on the second
quizzes of the unit. Use the following links to view some
