===== Linear Motion =====

(Lecture: 10 minutes)

    * Equations of motion and how to solve them

==== Reflections ====

This lecture was originally part of the
[[..:..:activities:rfact:rfthockey|Turntable Hockey]] activity.
The goal is to derive, and then solve, the differential equations which
describe linear motion as seen in a rotating frame.

The derivation is straightforward: Simply set the true accelaration equal to
zero in the modified second law, and write down the components in terms of
rotating coordinates.  The result is a system of coupled second-order ODEs.

The solution of these equations is not difficult, and is of possible interest
to students in its own right.  But there is no point in rushing through it.
A possibly better choice is to quickly derive the equations, then ask for
student feedback --- possibly as a SWBQ --- on ways to solve it.  The actual
solution can then be skipped --- but do emphasize that it is precisely the
solutions to these equations which are studied in the
[[..:..:activities:rfact:rfthockey|Turntable Hockey]] activity.
