Feedback first code

[mstoelzle]

Some feedback for the Fall_only_model.py:

• You need to include a plt.show() or plt.save() at the end to actually show the plot
• You need to put the main code, which initiates all the action, into the __main__ condition, to execute it when you run it as a script from the command line (https://docs.python.org/3/library/__main__.html)
• Add some code comments, what those parameters you specify actually physically mean
• You would call the timestep not t but rather dt. For the start, its sufficient to use a constant step size to integrate the physical system. Later, if you would introduce more nonlinear dynamics, you might want to use this solver for your system: https://docs.scipy.org/doc/scipy/reference/generated/scipy.integrate.solve_ivp.html

I think its a good start and I am excited to see where you will take the project
