Here is some background : I'm taking part in a programming challenge in which you control a racing pod that has to go from checkpoints to checkpoints to win a race. You are allowed to specify the thrust (in [0;100] ) of the pod and a target point.
I would like to know more about how the physic aspect of the pod is modeled inside the challenge.
So I did a first experiment : for the first 25 frames I set the thrust to 100, and the next 25 frames I set it to 0.
Here are the graphs :
I think one of the most interesting thing is the speed going negative shortly after stopping the thrust.
So from this data, with my limited knowledge of physics, I deduced that acceleration might be of the form acceleration = thrust - k.speed.
My question to you guys is, first do you recognize an obvious model to this ( considering the model simulating the pod physic shouldn't be very complex ) and secondly, can you suggest me a method to deduce the model from the data ?
If you think I should do another experiment with different conditions please let me know.
Thanks a lot.
PS : I can't post more than two links, I'll try and add acceleration graph and raw data file in a following reply.
