PhysLabJS is a small HTML/CSS/JavaScript application to create one or more small systems made of spheres interacting in a 2D plane. The interaction choosen is a simularione (very simplified) of a bidimesional attractive force.
It is made for fun only, it is not intende to be used for educational purposes.
Made with Konva.js.
This is an example a small system with 2 bodies:
This is how the application is after adding some system and a body:
The toolbar contains the main set of tool to manage the systems.
The button functions are as follows:
| Button | Function |
|---|---|
| Configuration | Set the main parameters of the application |
| Refresh | Restore original position of the bodies |
| Add | Add a new body to the current system (crete a new one if none esists) |
| Load | Load the systems from the local storage |
| Save | Save the systems in the local storage |
| Start | Start animating the interaction |
| Stop | Stop animating the interaxtion |
| Field | Description |
|---|---|
| Radius | Set the radius of the spherical body. Affect appearance and mass for the gravitational interaction |
| Density | Set the density of the spherical body. Affect mass for the gravitational interaction |
| Acceleration | Set the acceleration to which the body is subjected (both axis) |
| Speed | Set the speed to which the body is initially subjected (both axis) |
| Color | Set the color of the body |
| Motionless | Set whteher the body is motionless or not |
| Field | Description |
|---|---|
| Default Wall Elastic Coeff | Set the default value of the elastic coefficient of the walls, use when a new system is created |
| Default G constant | Set the default value of the constant interaction used to calculate the force, use when a new system is created |
| Acceleration vector | Acceleration vector properties group |
| Visibile | Set whether the vector is visible or not |
| Magnify | Set the magnifing factor for the vector |
| Color | Set the vector color |
| Speed vector | Speed vector properties group |
| Visibile | Set whether the vector is visible or not |
| Magnify | Set the magnifing factor for the vector |
| Color | Set the vector color |
Only a subset of the properties is changeable at the moment.
| Field | Description |
|---|---|
