Gravity changes, in two ways, the motion of objects
in freefall. There is the curvature that Einstein described
as coming from space-time. There are also times where
objects do not follow curves but instead are caused
to speed up.

If you picked a perfect circle for an orbit its motion
would be all curvature and no change in speed.
If you choose an object falling straight down
toward the center of gravity it is all speedup and
no curvilinear motion. But most of the time freefall
is the combination of both curvilinear motion and
a change in speed.

There really are two sides to gravity; weight and
freefall. But freefall is also dual as I have described.

Hope this helps someone to understand freefall
in a deeper way!
