Are all things in motion?
Is the world itself in motion?
Yes, everything in the world is, at least roughly, in motion because the Earth orbits the sun at a measurable velocity—not that I know this off-hand).
On a much smaller scale, of course, everything is in motion because, as far as we know, ALL matter is made up of electrons zipping around a nuclear core.

Yes, according to classical mechanics, all things are in motion relative to some frame of reference. However, in some cases, objects may appear to be at rest from a certain perspective.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
