Since the Earth is spinning, the objects in its surface are always changing direction, and thereby, changing velocity. So is this not an example of a non-inertial frame of reference?

Answer 1

Yes. It’s a rotating reference frame, but that rotation is rarely an issue for anything but the most precise measurements. The mass of the earth is just so much bigger.
