Know if entity phisics are anabled

hi, my queation is short, is possible to know if an entity have phisics or if is just a normal entity?

I think that the only way is to use a entity's flag set when you enable the object...
Code:

---

 
define phys_active, flag1;

...
my.phys_active = phent_settype(my,ph_rigid,ph_box);
...
