What is Physical Theatre?

In Friday's theatre class with Mrs. Weeks each of us brought in a sheet of paper with our "lifelines", and spent the class experimenting with the different ways we could physically act them out. Basically, we were interpreting our lives through physicality, and no words. As our introduction to the unit of physical theatre, along with Fuerzabruta!, this made me come up with some ideas as to what physical theatre really is:

The predomincance of communication through the body rather than through words.

A physical interpretation of theatre .

Working from the outside in?

Now, moving on from my initial thoughts, I can research physical theatre to gain some background on it before we move on in class.

"Physical theatre:
goes beyond verbal narrative, incorporating physical and visual elements on a level at least equal to verbal elements
is more than simply abstract movement – it includes some element of character, narrative, relationships, and interaction between the performers, not necessarily linear or obvious
includes a wide variety of styles, approaches, aesthetics – can include dance-theatre, movement theatre, clown, puppetry, mime, mask, vaudeville, and circus "

So, what does this mean?
From what I've read, it appears that physical theatre incorporates more sensory perception than other forms of theatre, because it is more than just verbal. However, despite my earlier impressions, words may still be used in physical theatre, because the physical and visual elements need to be "on a leel at least equal to verbal elements". And although physical may be very abstract, as I learned through seeing Fuerzabruta, it also incorporates other theatrical elements like "character, narrative, relationships, and interaction". So, physical theatre is more than just abstract movement. It still has the same basic elements as many other forms, but its presentation is less obvious, or linearally presented to the audience.

I look forward to seeing if this interpretation still seems true by the end of the physical theatre unit.
