Interactive mechanics applets

For those times when reality isn’t enough.

1. Various mechanics simulations.  The roller coaster with flight contains a substantial amount of the physics we’ll do this semester.
2. Several moderately interactive mechanics simulations.
3. Projectile motion describes anything thrown through the air.  It really doesn’t have to be cannonballs.  Yet people keep on making cannon simulations; this one even has  explosion-type sounds on impact.  Moreover, it comes from Japan where you’d think they’d be particularly sensitive about the historic connection between physics and the technology of warfare.
