Physics 409: Classical Mechanics
Fall ‘10
28 September 2010
Lecture schedule
:
28 September: Chapter 3;
30 September: Chapter Test #2 on Ch. 2 (more problems setting up and
solving Lagrangians, including Lagrange multipliers, plus calculus of
variations problems)
5 October: Ch. 3, Sec 3.9, 3.10
Review Session: Tuesday 28 September, 3:30 until 6pm, Rm. 202
Reading Tips for 5 October
: For 5 October: What is the LaplaceRungeLenz vector?
What is its
significance? How do you calculate a scattering cross section from the solution to the twobody
central force problem?
Homework Set #6:
Due Tuesday, 5 October
(1)
GPS Prob. 3.33 (in 2
rd
ed. #3.1) The equation for a paraboloid of revolution is
z = a
(
x
2
+
y
2
).
(2)
GPS
Prob. 3.11 (in 2
rd
ed. #3.3)
(3)
GPS Problem 3.13
(2
nd
ed. #3.6)
(4)
A particle of mass
m
moves in a central force field given by the potential
V
(
r
) =
k
ln(
r
/
a
),
where
k
and
a
are positive constants. Note that this potential is
attractive
; it arises from an
infinite line of mass.
