| Ray Optics Simulation and Calculator |
| This application will simulate reflection and refraction of light with optics such as: A single ray of light defined by two points, A parallel beam of rays emerges from a line-segment, with density controlled by the "Ray density" slider, A mirror whose shape is part of a circle, which is defined by three points., Glass with any shapes constructed from line segments and circular arcs, including prisms and "spherical" lenses., etc. |

| Resolution Force Vector Components Animation and Calculator |
| When solving physics problems, it is often helpful to replace one force by a combination of two forces with given directions. Of course, these two forces must be equivalent to the given one. This means that their vector sum must agree with the given force. If this condition is fulfilled, we say that the force has been resolved into components. |

| Constant Acceleration and Motion Animation and Calculator |
| This application shows a car moving with constant acceleration. The lower control panel contains text fields where you can vary the values of initial position, initial velocity and acceleration (don't forget to press the "Enter" key!). By using the buttons at the bottom you can bring the car back to its initial position or stop and resume the simulation. If you choose the option "Slow motion", the movement will be ten times slower. |

| Centrifugal Force Equations and Calculator |
| Centrifugal Force equations and calculator. When a body of mass rotates about an axis it exerts an outward radial force called centrifugal force upon the axis or any arm or cord from the axis that restrains it from moving in a straight (tangential) line. |
|
| Centripetal Acceleration Equations and Calculator |
| Centripetal Acceleration and force equation and calculator defines the distance that is covered and the direction of the movement. Since the velocity vector (the direction) of a body changes when moved in a circle - there is an acceleration. |
