What is air-resistance-free-fall-simulator?

This is a small Python application, built with the Tkinter graphical toolkit, that simulates an object falling under gravity while accounting for air resistance. Instead of using a single formula to jump straight to an answer, it works by stepping through the fall frame by frame, recalculating the object's speed and position at each small time step, which is how you get realistic effects like terminal velocity, the point where air resistance balances gravity and the object stops speeding up. The README is short and describes this as one of the author's first programming projects, made while they were learning Python, as a way to practice and improve their skills. Because of that, it is best understood as a learning exercise rather than a polished tool meant for outside users, though its features already cover the basics of this kind of physics simulation. You can adjust several variables before running a simulation, including the object's mass, its starting velocity and height, the drag coefficient, air density, and surface area, all of which affect how quickly the object falls and how strongly air resistance slows it down. There is also a menu for selecting a preset object and for choosing the simulation's time step, along with an easier and expanded time selection menu. The author lists a few possible future improvements they have in mind but have not yet built, including adding graphs of the results, other kinds of simulations, support for gravity on other planets, and a real time simulation mode. As it stands today, this is a desktop simulation tool for anyone curious about how air resistance changes a falling object's motion, and it doubles as an example of an early Python project.
