Study guide - Momentum Conservation and Electrostatics

    Physical Systems 1998-99
    with E.J. Zita
    Overview            Team 1            Team 2            Team 3

    Overview:  read Tipler Ch.39, Barger and Olsson Ch.4, and Griffiths EM Ch.2.

    On Tuesday morning ( Waves and Oscillations; Modern and Thermal), Zita will introduce relativistic momentum and energy and conservation of momentum .  Then Teams 1 and 2 have about half an hour each to do their examples and get us started on some group work.  Everyone should bring a written question on each chapter.

    On Tuesday afternoon (E&M, Quantum, Stellar Interiors), Zita will introduce electrostatics.  Then Team 3 will have about half an hour to do their example and get us started on some homework.  Everyone should bring a written question on the reading.

    Team 1: Barger and Olsson Ch.4:  Conservation of Momentum

    _________, and  _________

    Carefully work through Section 4.3 on Elastic collisions.
    Then use it to set up problem 4-9, p.132

    Note your questions as you work through this, and write them down.
    Questions which you answer in the process:  pose these to the class, to help them gain the understanding you just achieved.
    Questions which you still have:  ask Zita in class.

    Prepare the set-up for presentation to the class in under half an hour.  Be careful to define terms (with units) and explicitly state any assumptions you make.   Draw enlightening diagrams and plots.  You don't have to solve the problem - get as far as you reasonably can on it, and Zita will help with the rest.

    Then help the class get started on working #9 together.  If there is time after that, Zita will discuss inelastic collisions.

    Team 2:  Tipler Ch.39:  Relativistic Momentum and Energy

    ____________, and  _________
    Read carefully through Example 39-10 on p.1266
    Then do #50 as far as you can.

    Note your questions as you work through this, and write them down.
    Questions which you answer in the process:  pose these to the class, to help them gain the understanding you just achieved.
    Questions which you still have:  ask Zita in class.

    Prepare #50 for presentation to the class in under half an hour.  Zita will derive relativistic length, momentum, and energy first. Be careful to define terms (with units) and explicitly state any assumptions you make.   Draw enlightening diagrams and plots.

    Then help the class get started on working #57 together.

    Team 3:   Griffiths EM Ch.2:  Electrostatics

    __________, and  _________
    Read carefully through Example 2 on p.73.
    Then do Problem 2.8 on p.77 as far as you can.

    Note your questions as you work through this, and write them down.
    Questions which you answer in the process:  pose these to the class, to help them gain the understanding you just achieved.
    Questions which you still have:  ask Zita in class.

    Prepare #2.8 for presentation to the class in about half an hour.  Zita will help you finish it, if you like.  Be careful to define terms (with units) and explicitly state any assumptions you make.   Draw enlightening diagrams and plots.

    Then help the class work together to start #2.15.  If there is time, Zita will demonstrate how to do the problem with electrostatic potentials.
