discussion with teacher
For pt 3 &4, our purpose is to really focus on what happen during the collision. Upon collision, the colliding bodies undergo periods of deformation and then restoration, so the force during collision will not be constant. Nevertheless, at any instant during collision, the forces acting on body 1 and 2 will always be the same. This is a very important concept from NTL that we want to emphasize to students. Moreover, this is similar to the graph in TYS N04/3/2.
We hope you can help us change the time scale of the graph, so that we can amplify the time during collision.
For that TYS qns I mentioned, the F-t graph is a curve (which i think might be harder for programming)
I was thinking more of a triangle instead of a curve, and the inverted triangle that is of cos symmetrical. Add more frames/steps during the period of collision? In this case, it will be obvious to the users that any pt in time during the collision, the forces are always equal (one positive, one negative)
[b][color=blue]if it is a triangle, it is done
it zoom in, select data tool by right click and select the Ft graph
it is a triangle impulse, not a curve impulse, the concepts is still
the same, forces F1 n F2 are equal and opposite act on different
the time scale cannot zoom in during collision, because the computer
model currently assumes instant re-bounce (idealistic), really touch
and go, no spring like deformation
to get a wave impulse like in TYS N04/3/2, i need to reprogram the
collision for all cases of collision e=0, 0 < e < 1, e=1 etc. which the
curve impulse is valid for 0 < e < 1, e=1 etc, but not for e=0 i think.
so it is rather complex.[/color][/b]
