Concepts & Terms for  CH's  5 & 6  (Work, Energy, Momentum, Impulse)

CH 5
Definition of Work (note direction of force relative to displacement)
Work done by Gravity
Work done by Friction
Defintion of Energy in general
Definitions of  Kinetic Energy, Gravitational Potential Energy, Elastic (spring) Potential Energy
Work-Energy Theorem
Conservative Forces versus Non-Conservative Forces  (and the work done by the same)
Be able to identify the various forms of Energy and examples of Conservative vs Non-Conservative Forces
Principle of Conservation of Energy (and know what is meant by an "isolated" system)
Definition of Power
TEXT EXAMPLES  5.5, 5.7, 5.8, 5.11   are useful to study in addition to the sample Test questions posted on the course webpage

CH 6
Definition of Momentum (note it is a vector !)
Definition of Impulse  (also a vector)
Impulse-Momentum Theorem  and connection to Newton's 2nd law
Principle of Conservation of Momentum
Elastic versus Inelastic Collisions  (Know which quantities are conserved and which are not)
NOTE EXAMPLES of collision types comparing Average Force magnitude and Time of contact:
See numerous examples on Page 163, 164, and 165
TEXT EXAMPLES 6.1, 6.4, 6.6, 6.7   are useful to study in addition to the sample Test questions posted on the course webpage
