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?

Yes. You can use a [Foucault pendulum](https://en.wikipedia.org/wiki/Foucault_pendulum) to verify this fact. They need to be large to work well but they’re common at science museums.
