Answer:
Well we all know the term "Personal Space," and "Personal Bubble." Right?
But what do they mean?
"The physical space immediately surrounding someone, into which any encroachment feels threatening to or uncomfortable for them."
Now we can see Physical and personal space are similar. Yet, Personal space is combined with someone's preference of space.
Physical space is not tied to emotion. Its "In a way that relates to the real world and things perceived through the senses as opposed to the mind."
Hope this helps!
