The molecular movement or speed creates friction and thus heat. Heat is an energy change, thus we have absorption or energy reduction.

That's the one. I remember learning this and was like ohhhh, that makes sense now...
Cheaper foam might not be Open Cell, if it's not open cell it's a waste of time and still very reflective. Be careful when buying cheap foam you might be getting conned.
I've got fiber glass panels in my studio, corner bass traps and will be buying some foam soon too. There is a health concern out there but many debunk it. The main concern is the glue, what keeps the panel together. This glue can give off harmful VOC's in some brands (most) basically everything gives off VOC's that we aren't aware of. Normal studio foam can have them too, your carpets, especially paint. The actual fibers in these panels are 'Apparently' easily dispelled from your lungs, not like asbestos at all. As for these covers, they do nothing to prevent VOC release! So airing them off outside for a long time is recommended. Some of the pro panels, Like Real Traps possibly Gik etc are now saying they use super friendly slabs in their panels.
A lot of these guys are quite old and have worked in fiber studios all their lives, yet don't have lung problems so can it be that bad??? I'm not sure myself, it is worrying though. Possibly do a search on how many studio gods died of cancer at an early age.
