Thank you We sneak and here's your shmoop du jour
- 00:05
Brought to you by quirks what's with the weird name
- 00:09
Because that's just how physicists get crazy All right question
- 00:14
Can a cork be described as a system and hear
- 00:18
the potential answers going Yes yes No no where's Our

dark force All right well first of all what the
- 00:25
heck is a cork Well the cork is the smallest
- 00:27
particle that we currently know of neutrons and protons are
- 00:31
made of corks And as you know neutrons and protons
- 00:34
are pretty darn small themselves And remember a system is
- 00:37
a collection of objects fields and forces that influence each
- 00:41
other right The system also has an internal structure and
- 00:45
that structure determines the relationship between the objects in a
- 00:48
system Well since a cork is the smallest particle that
- 00:52
we know of it doesn't have a structure There are
- 00:55
no little pork lings inside the court It just is
- 00:58
what it is without an internal structure A core can't
- 01:01
be a system So our answer his options see No
- 01:04
it has no internal structure Courts do have mass in
- 01:07
the occupy space We also carry charges and interact with
- 01:11
other particles but none of those are defining characteristics of
- 01:15
the systems So answers eh and beer incorrect and answer
- 01:18
D is wrong too It doesn't matter if a system
- 01:20
is larger small in this case it's the internal structure
- 01:23
that matters now Maybe someday when we're hotshot particle physicists
- 01:27
will discover that corks are actually made of even smaller
- 01:31
particles But don't worry we'll name the new particles something
- 01:34
reasonable like the small a tron or something like that 00:01:38.411 --> [endTime] Yeah
