I've got a rather humiliating question considering newton's
third law "If an object A exterts a force on object B, then
object B exerts an equal but opposite force on object A" ->
$F_1=-F_2$ Considering that, why is there motion at all? Should
not all forces even themselves out, so nothing moves at all?
When I push a table using my finger, the table applies the same
force onto my finger like my finger does on the table just with
an opposing direction, nothing happens except that I feel the
opposing force. But why can I push a box on a table by applying
force ($F=ma$) on one side, obviously outbalancing the force the
box has on my finger and at the same time outbalancing the
friction the box has on the table? I obviously have the greater
mass and acceleration as for example the matchbox on the table
and thusly I can move it, but shouldn't the third law prevent
that from even happening? Shouldn't the matchbox just
accommodate to said force and applying same force to me in
opposing direction? I've found a lot of
