GRAVITY Nu is software for visualization of gravitational force effects between N objects.
In order to predict/calculate object data (position and velocity) in future or past time (within limits of calculation) one needs object mass, initial position and initial velocity vector at some initial moment of time. Data is calculated and displayed in SI units (second, meter, kg, meter/second etc.).
Position data is defined in (x,y,z) components and velocity data is defined in (x,y,z) vector components in Cartesian coordinate system.
There is no limitation in parameters - object will behave just like they behave in the real world so, be careful with initial data - you will see same behaviour as in real world with real objects - again, within variables, calculation and display limitations.
You can input the project and object data via software interface (Gravity Editor) or directly in simple TXT file.
The program comes with predefined object template for the Solar System, but you may also create a new object by adding your custom-defined parameters. You can then use the included analysis tools to observe the movement of your ellipsoid.
If you want to define various objects, you need to specify their respective densities, masses, positions and velocities. The software automatically defines the objects you create as spheres.
You can use Gravity Nu to calculate the trajectories and movements of objects irrespective of their masses or distances, which allows you to estimate the likely gravitational behaviors of both small objects and whole planets. The program displays data about speed and current position of an object. It allows you to set the value of G constant representing gravitational acceleration for each project.
Once you have defined the required parameters, the program will display animated gravity simulations when you click the Play button, and you may adjust the simulations by changing the number of frames per second. You can specify any value between one and 50 depending on your preferences and system. You may also zoom either in or out using the mouse wheel for better observation.
You must understand Cartesian coordinate system and vectors to use Gravity Nu, as it defines data in X, Y, Z vector components.
What´s New in version 2.02:
- NEW : IMPULSE EDITOR - simple utility for defining the sequence of impulses applied on object in order to change its position and velocity at some particular moment in time.
