An objects speed or motion is measured by distance divided by time.
by using lasers.
retrograde motion
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.
the speed of motion is determined by how fast the object in motion is traveling along with the distance it has traveled. the direction of motion can be discovered by either using a frame of reference (point of comparison) or simple devices such as a compass.
It is used to determine the distance between objects such as celestial bodies. Example: the distance of stars from the earth can be measured by using the parallax.
Each human eye can clearly see letters of a certain size at a certain distance. The Snellen Eye Test uses this to determine that distance for each eye. The eyes do not work together to see objects clearly.
It will have no equilibruim and when you are pushing it you are using a force

According to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. It is the natural tendency of objects to keep on doing what they are doing. All objects resist changes in their state of motion. In the absence of an unbalanced force, an object in motion will maintain this state of motion. This is often called the law of inertia.
