Usage

This program uses F as following, to calculate the force applied on the flying objects.

$$F = G. \frac{m_1.m_2}{d²} $$

The point is to simulate how gravitational forces are moving objects through space. Two Spatial Bodies are displayed on the screen while flying objects go through $$x$$ and are being pulled by their gravitational forces. You can adjust the numbers of objects, the speed of the objects, the constant $$G$$, and the mass and coordonates of each spatial body.

Getting Started

To get a local copy up and running, follow these simple steps.

Prerequisites

This is an example of how to list things you need to use the software and how to install them.

• on Arch Linux : Gcc and make are already installed.
• on Ubuntu : Verify that gcc and make are installed:

  sudo apt install build-essential git

Installation

1. Clone the repo

   git clone https://github.com/MountainEnjoyer/GravitationalForces.git

2. Install Raylib

• On Arch linux:

  sudo pacman -S raylib

• On Ubuntu:

  sudo apt install raylib

3. Change the values of the simulation:

    #define WIDTH 1200
    #define HEIGHT 900
    #define FPS 60
    #define OBJ 100
    #define R_OBJ 2
    #define MASS_OBJ 10
    #define XSPEED_OBJ 10
    #define YSPEED_OBJ 0
    #define BODY 2
    #define MASS1 100
    #define MASS2 500
    #define G 0.6 // supposed to be 6.67*powf(10,-11);
    #define L_TRAIL 250

4. Comile and execute by running:

    make

5. You can press ENTER to replay the simulation and ESC to exit it.
