This applet shows the traditional problem of shooting a cannonball. While there is no pretty cannon, it does use correct units and gives a clear picture of trajectories. There are options to show trails of the projectile or to turn on a simple air friction.The Ballistic Simulator (Cannon)
This Java applet allows the user to adjust various parameters (angle, velocity, gravity, windage, density, drag) in a projectile simulation. When all parameters are correct the projectile will hit the target verifying the student's calculations.
This java applet lets you change wave speed and source speed to illustrate these phenomena.
Java Applet by Fu-Kwun Hwang that demonstrates properties of lenses. An object or the lense can be dragged and dropped and the focus length of the lense can be varied. Real and virtual images, parameters and traces are viewed graphically.
