For a start ...
 contact
 two masses come in contact via a spring
 proj
 introduction to lagrangians with projectile motion
 yank
 mass suspended by upper cord; yank on lower cord to break lower one before
upper one

And then ...
 bounce4
 a small ball rebounds to a great height after striking a large ball which
was released just below it.
 conserve
 check force components to see if they come from a conservative force.
Then see if line integral vanishes.
 cuplosc
 coupled oscillator solution, with normal modes
drivnosc  amplitude
and phase response of a driven, damped oscillator
 eulerAn2
 use rotation matrices to animate motion when one or more Euler angles
change in rigid body rotation
 fouclt
 foucault pendulum, with template for students
 rotspr
 rotating massspring system using lagrangian
 table
 mass m on a frictionless table w/cord through hole in tabletop to mass
M hanging below
 yankadv
 advanced version of yank no approximations
