An excellent Skate Park (which is roller-coasters to you)

This applet shows an image of a sky diver, who then opens a parachute. It simultaneously displays the two forces on her, one constant, one changing, and the effect on the a = F/m calculation.  {To freeze it, try clicking and holding somewhere in the images}

This is another good terminal velocity applet, which works in separate pages to show the forces. Nicely done.

For terminal velocity, this applet shows two objects, oriented to have different amounts of air resistance. It plots the v/t graph as they fall.

Terminal velocity nicely shown.  You can change the density of the medium, the mass of the ball, or its radius, and the applet plots x, v, and a, simultaneously.  (It's a Gizmo, which you can only watch once...)

The Moving Man, with displacement, velocity, and acceleration, graphs.

This is a nice GIZMO F=ma applet with a fan-cart, graphs of its motion, different masses and forces.

This is a nice applet for reaction time for braking when the lights change.
