What is Circular motion ??
The direction of a body's motion is constantly changing when it
moves in a circle at a steady speed.

this is nothen, circular motion any children can do

what is spherical motion, that is the question

after answering this one then try what is intrinsic 4d motion

Does this then become an acceleration each moment to change the straight
line directional vector?

That was resolved to be c cubed, I believe.

It is rotation along a circle stupid.

What if the surface is based on Riemann geometry? What is a
circle then?

What if you are rotating y=x^2 around the x-axis? What
is a circular motion then? (assume Euclidean geometry;
then repeat for two other geometries.)

Thanks! Then why such a hullaballoo made in the past over the concept
that light bends in a gravitational field? Surely in the M-M experiment
the travelling back and forth light had to bend with the Earth in order for
it to appear that it was going in a straight line back and forth?

Because Newtonian theory says gravity affects masses,
and light is massless.

The M-M experiment has nothing to do with gravitational
bending of light. The earth doesn't have enough gravity to cause
a noticeable effect. The answer to your question is "no". The
light doesn't have to "bend with the earth to appear to be going
in a straight line back and forth".

By "bend with the earth" do you mean follow the curve
of the earth, so that it would be the same height above
the earth's surface everywhere? Light doesn't do that.

Newtonian theory says light curves, just like this ball:

By "bend with the earth" I mean the Earth rotates, and
yes, light does curve.
