Corrections for NST IB Physics B `Classical Dynamics'
Corrections to the printed handouts/examples sheets.
Handout II:
Slide 80: second line, should say ``... force ${\bf F}_0$
...''.
Slide 82: the last part of the PE is missing an $h$, and
should say ``... $\approx m g h \theta^2/2$.
Slide 97: if the direction of $\Delta p$ is in the $+z$
direction, then $\omega_x (t=0)$ is positive, and $\omega_y (t=0)$ is
negative. So, it would be better to say $|\omega_x (t=0)|=(\Delta p)y$
and $|\omega_y (t=0)|=(\Delta p)x$. (The wrong/undefined signs for
$\omega_x$ and $\omega_y$ at $t=0$ are not important for what is
subsequently needed, i.e. $\omega_x^2 + \omega_y^2$ at $t=0$.)
Slide 100: the second diagram has axis 1 in the wrong
direction, it should be in the opposite direction (this is not important
for the derivation of the space frequency on this slide, which uses the
magnitude of $\dot{\omega}_1$ to derive $\Omega_{\rm s}$).
Handout IV:
Slide 218: ``... do to ...'' should be ``... due to ...''.
Please let me know of any other errors.
