I understand GR explains motion under a gravitational field a curvature of
space. I have NO problem with this. The bending or light during a solar
eclipse proved GR correct.

But how does GR explain a stationary object exerting a force while on the
surface of a planet?

Dear Danny Dot:

Not "space"... spacetime.


The force is an inertial force, as the surface of the planet
accelerates the "stationary object" into a circular orbit. An
orbit for which it has insufficient momentum to maintain on its
own.

Because every bit of matter tends to move towards its gravitating center
which is the center of earth in a local way while altogether they move
towards the solar system's gravitational center which simultaneously moves
towards the galactic center and so on and so forth towards the center of the
total Universe which maybe in fact more than one Universe or which could be
termed 'Entirety' [including our Universe {known and visible} and if they
exist more such Universes]
