There are many similar applets, and this one is no better or worse than most.

Applet is supposed to model projectile motion given certain initial conditions. Unfortunately, it simply does not work. For example, the projectile returns to Earth even though I entered 0 for g. Increasing the velocity at times decreased the range, and so on. Something is seriously wrong with the numerical algorithm.

Technical Remarks:

I could not get rid of the popup window, and once the system is halted there is no way to resume the motion --- a new projectile must be fired. That is a serious limitation for an educator.
