I 'm pusing mass m on table in my room
my finger is registering resistance
( direction is important or all forces are the same ? )


can I measure how will change force that table's leg give to floore ?




Respect to what in space my finger is registering different forces ?


Right side of my picture

Inside rocket light always fall down

what about mass m ( mass m can become satellite ? ( if we are on planet ) can I recognize that I'm inside rocket ? )
