- Projectile -- "This Java Applet simulates a projectile being launch from ground level with an intial velocity (Vo) at an angle (Ø)."
- Ballistic Trajectory Tutorial -- "The tutorial will help you to visualize the
flight path, speed, and duration of projectiles fired at different initial angles and velocities."
- Damped Mass-on-a-Spring Java Applet -- Illustrates the motion of a mass attached to a string. You can adjust the mass, the spring constant k, and the damping.

- Hard Spheres -- "This is a Java Applet showing the distribution function of a group of randomly colliding hardspheres."
- Potential Flow Applet -- "Build up incompressible, irrotational flows by superposition of a free-stream velocity and various singular solutions to Laplace's equation (sources, sinks, vortices and doublets). Once the flow is built up, the student can visualize the flow, by plotting streamlines, velocity vectors and isopotential lines."
- Venturi Tube Simulation -- Change the venturi tube radius and flow rate and calculate velocity, pressure, head, etc.
Heat and Thermodynamics

Light and Optics
- Light Refraction -- Input incident angle and wavelength and index of refraction, and calculate refracted wavelength and angle.
- Young's Double Slit Interference -- When a light source is split by passing it through two slits and projected onto a screen, an interference pattern is generated. Adjust the distance, d, between the slits and the distance, L, to the screen, and see the generated pattern.
- Optical Table 1.0 -- This applet "visually traces the paths of rays. It is intended to teach the principles of reflection,
refraction, and optics to high school and undergraduate students."
ElectroMagnetism

It illustrates several important concepts in statistical mechanics/kinetic theory, such as: mean free path and average time between collisions, the approach to thermal equilibrium and the Maxwell-Boltzmann speed distribution, and the question of macroscopic irreversibility vs. microscopic reversibility."
- Schrödinger Wave Equation Simulation -- The Schrödinger equation "... is a parabolic partial differential equation in space and time
commonly refered to as the wave equation...[and]...is of fundamental importance in a wide range of physical phenomena where quantum mechanics is important. This applet "allows user control of the simulation parameters and realtime numerical solutions to the wave equation."
