I modified one of the examples to test how fast an object falls.
The implication of this is we need to either model at the ratio of 1 darkbasic unit = 1 meter or scale to get this ratio.
If i wish to use other units mm or inches you can simply change the gravity constant.
My question is do I have to change any other constants to make the models react correctly?
