what is a force seems to be an idea that
a lot of people are confused about it's
like Star Wars is the only source of
knowledge what is a force um it's like G
die for like force is how you raise
x-wings out of swamps you just
concentrate what would you say a forces
other than
Jedi but out outside of Star Wars a
force is energy and
mass so if you have a huge thing moving
really fast you got a lot of force it's
like getting hit by a truck as opposed
to getting hit by this tennis ball um
force is energy um that comes from
somewhere something that exerts energy
on all other matter the
movement the movement of something in
One Direction
and
the
atmosphere
listen I don't know it's soort this
Indescribable thing that kind of keeps
us from flying off into space nobody
really knows what it's um about it's
just a
theoretical kind of thing and that
should teach me to interview philosophy
students but contrary to what she said
there were some people who knew what
force was about something that makes
something move from its original
position how you Propel something or how
you get something to move or how to
shape reshape something it's a kind of
uh attraction or direction or something
like that that an object has on it yeah
push yeah push or uh a PO sure yes okay
it took some coaching but force is
essentially just a push or a pull so
then I asked people what forces are
acting on you right now most could
identify a downward gravitational force
towards the center of the Earth but uh
then things got a little bit hazy can
you tell me about the forces on you at
the moment um well probably there's a
big force uh downwards towards the
center of the earth which is uh that's
that's gravity what we call gravity I
guess well the gravity of Earth where is
it how does it act on you well it keeps
me on the earth I it just I don't I
don't fly away I would be standing on
the earth and it's pulling me down and
making sure that I'm stuck to the Earth
yeah okay what other forces are on you
are there any other forces on you uh
there are there's air pressure forces
around me uh there's my own muscular
forces giving me up my skeletal forces
those kind of things uh and also then uh
different uh sort of weather or climatic
conditions in terms of like wind weather
that sort of thing or just normal
gravity is it what's keeping me on the
ground isn't that gravity so this is a
gravitational force pulling you down
yeah um any other forces that are acting
on you B friction like on me right now
on you right now I can't think of
anything ex else except gravity only one
force is I mean Sur there's like a lot
of small ones but let me put this to you
if there's only one force on an object
what does it
do uh it goes towards it but there is
another force acting on you which is a
pretty important one cuz there's like
there's a force acting down right that's
a gravitational force mhm what about a
force acting
up no no up forces not that I can think
of okay so what forces are acting on you
right
now
