An objects speed or motion is measured by distance divided by time.
by using lasers.
retrograde motion
The apparent motion of objects in the sky depends on the motions of Earth.
They take objects that are at a distance and magnify them using mirrors and/or lenses.
Weight,distance,& volume
They take objects that are at a distance and magnify them using mirrors and/or lenses.
The answer depends on what distance is being determined: the distance to stars using parallax, the distance to aircraft using radar, the distance from one city to another partway around the earth, the distance between two nearby objects.
It will have no equilibruim and when you are pushing it you are using a force

The work of the art of mona lisa.
Distance is measured using reference points therefore distance, between objects, is relative. Some of the units used can be absolute, the separation between two or more points cannot.
Let's say we want to measure the distance between objects A and B. First, we measure the distance from the Earth(point E) to these objects(using Doppler-shifts).Then, we measure the angle AEB.We now know the lengths of two sides, and the angle between them. That's how we find the distance AB.
