Hi group, I'm looking for free software which is suited for modelling. For example, I'd like to simulate a flying cannonball with something like this:
Model: vy(t) = vy(t) + ay * dt y(t) = y(t) + vy(t) * dt x(t) = x(t) + vx(t) * dt t = t + dt Initial conditions: ay = 9.8 vy = 120 vx = 60 t = 0 dt = 0.1 It is primarily intented to teach students how a mathematical model works. There are several proprietary programs available. In the Netherlands, probably all high schools use the program Coach for driving experiments, doing modelling, etc. in physics, chemistry and biology. It is a dutch program, so probably very few of you will have heard of it. I think it may be possible to do this in basically every algebra system, like octave, yacas, etc. but I'd like to do this as easily as possible. Any suggestions? Thanks! David -- Hi!
