if you feel a pressure in your feet, then it is a force

Swing an object on a string. There is one force on
the object... that of the string.

There is one force in a body at rest on the surface
of a planet. That of the planet pushing up on "the
feet". Gravity is not a force. "Lithospheric friction" is.

Dear mister SMith

aparently what you say makes sense

let us just call all forces for lithospheric friction

i tell you what, it feels like a force - it is a force, by the
pure definition of a very force

Good. Then an object in orbit around a larger body, feels no
force. Gravitation is not a force.

Do you "communicate" with material objects so you know what they
"feel"?

I mean, words like, 'exists", "real", "ficticious", etc, have no place
in physics. A force is measured by measuring acceleration. If there is
acceleration, there is force. Nothing more into it, just a definition
of Newtonian mechanics.

If someone says: there "are" no forces in the world, he is doing
metaphysics, not physics.
