Edwin Hubble demonstrated that all galaxies and distant astronomical objects were moving away from us$,$ as predicted by a universal expansion. Using observations, he showed that all objects are moving away from us$,$ and that their speed is proportional to their distance, a feature of metric expansion. In $2001,$ Wendy Freedman determined space to expand at $72$ kilometers per second per megaparsec $-$ roughly $3\mathrm{.}3$ million light years $-$ meaning that for every $3\mathrm{.}3$ million light years further away from the earth you are, the matter where you are, you would be moving away from earth $72$ kilometers a second faster.

Step $1$: In your post, discuss how these observations relate to velocity and acceleration. If you are standing still, are you still moving? Are you accelerating? Support your assertion with reasoning based on the above statements.
