Success in the portion of our class covering the Conservation of
Momentum for a system of particles is determined by your being able
to accomplish the tasks listed below.  The major objectives are
listed by number.  The list under each major objective includes
both subtopics of that objective (usually topics which are
required for a complete understanding of that major objective)
and also the multiple representations of the task in which you
are expected to be proficient.

1. Understand and apply Newton's Second Law for a system of
particles
Definition of the center of mass of a system of particles
Velocity of the center of mass
Acceleration of the center of mass
The difference between internal and external forces in a
system of particles
The First Law for a system of particles, and its relation
to Conservation of Momentum for the system and to the
velocity of the center of mass of the system

2. Understand and apply the Impulse-Momentum Theorem for
a single particle
Definition of momentum
Relation between momentum and kinetic energy
Definition of impulse
Definition of time-average force
Origin of the Impulse-Momentum Theorem

3. Understand and apply the principle of Conservation of
Momentum for a system of particles
Requirements for validity of Momentum Conservation for
a system of particles
Relation to Impulse-Momentum Theorem for a system of particles
Applications in one or two dimensions
Applications for explosions
Applications for perfectly inelastic collisions
Definition of a perfectly inelastic collision
Applications for elastic collisions
Definition of an elastic collision
Relation to velocity of system center-of-mass
Applications requiring an understanding of both Energy
and Momentum Conservation (eg. the ballistic pendulum)
