The C++ Project (pro v2)
About The C++ Project (pro v2)
The software shows elementary simulations of classical physics. There are nineteen simulations ready to run, and it is possible to create personalized simulations, too. The name of this edition is “pro v2”, and it has all the simulations of the “free” and “pro edition”, but with new graphics and effects. For example, its balls are “antialiased”, and the echo effect is different.
It has multi-ball collisions, simulations to study the concepts of force and energy, and “gravitational simulations” (using gravitational forces).
In the simulation “Fifty balls; without gravity (gas simulation approximation). Piston under gravity.” it is possible to study the concepts of force and energy. The user can increase the system’s energy in real-time (through heat, using the keys -> and <-) and can verify the elevation, on average, of the piston’s potential energy (work done by the system). So, the program may illustrate the First Law of Thermodynamics, approximately.
It has a gravitational simulation named “A Fictional Universe”. Sometimes, it is possible to watch the formation of objects representing a planet and its satellite! There are two versions: the standard (the same as in the “free edition” or in the “programmable”) and the “unstable” simulation, where the “fictional universe” is constantly changing.
The “information propagation” simulation illustrates the propagation of information based on a simplified model (using the collisions of the balls). We can see the effect of the “memory” duration in the propagation and the result of several ball velocities. It is helpful to illustrate and reflect on what we see in our highly interconnected society.
It is possible to make or edit a .txt file (plain text), following the instructions, to change all the values of parameters and create specialized simulations.
We can simulate, for example, a simplified satellite launching, where one ball will be the planet and the other the satellite. The challenge is to choose the launching and orbit speeds. Also, there is a “Satellite Launching” simulation ready to run (with data already programmed).
