  Its like if your actor slides across the screen , it will stop faster if you give it a higher drag value , in physics terms , its like fluid resistance , the higher the value , the higher the resistance
  Same goes for angular drag , but its referring to *rotation*
  
  Best way to understand this is to actually test it in the viewer , and see the result.
  if you make some testing , i suggest you put very high or very low values , to see a noticeable difference , like 0 to low , and 1000 to high .
  
  Cheers

  Drag is basically the amount of friction from the air or non-physical objects. You use friction to affect how your actors slide against each other and you use drag to affect how an actor is affected when its moving around by itself with nothing touching it.
  
  Definitely try POMs suggestions for testing to better understand, but I would use his suggestions on the cannon demo. Set different drag and angular drag levels on the cannon ball and then play and fire and watch how it reacts differently.
