Here is the fact:

rope<elastic<<cloth<<metal bar<<rubber(!)<<metal plate<rocket
I think it can be useful

The strangest thing is that rubber falls faster than metal plate :shock:.

Here is the proof:

In fact, it isn't that strange. After our last talk, I figured out that width of rubber is less than width of metal plate - you can see this in "Free" mode. :)

interesting, what do you think of my experiment? i tried to remove the effect of the slack rope and weight of the scales themselves having any other effects on the materials....see the rightmost bits to show the amount of rope needed to balance one unit of metal bar for each pair of scales. and then two untis of metal bar against two lots of the rope needed to balance one.

Very interesting result with the cloth...

edit: i decided to test the scales a bit more. physics is definitely not right in this game as 2 units of metal bar never balances with 2 lots of 1 unit...

oh well.

yea, this game has issues with conservation of energy, which is why it is possible to create an enternal motor with the force.
