What are the default values for all the physics properties?

Okay, for the mass it depends on the (created) entity and its form. And you can get the value by using pXent_getmass...

But what about friction, damping, elasticity etc. ??
I can't find any default values in the manual and there are no get-commands as well.

That's what I was asking myself today, too. It should be added to the manual...

right, I opened a "blame the manual" thread
