Moving objects or celestial bodies such as stars can also be used as reference points in navigation and positioning. These objects can provide constant or predictable movement that can help determine direction or orientation.
negative
If the force moving an object points partially in the opposite direction of the object's motion, work is considered to be negative. This is because the force is acting against the direction of motion, reducing the overall work done on the object.
Any object can be used as the reference. There's no such thing as an 'unmoving' object. It's only unmoving relative to itself or to other things that are moving exactly the same as the object. That's the whole reason that you need a reference point.
An object's length is the physical extent along a straight line or path. The direction an object has moved from its starting point is the vector that points from the initial position to the final position of the object.
A reference point is an object or point from which movement is determined. It serves as a fixed location or frame of reference that helps to describe the motion of other objects or points in relation to it.
Two nonmoving objects that are useful reference points are a stationary pole or a fixed building. These objects can serve as points of comparison or markers to determine direction, distance, or positioning.
Points are the only such objects.
It can allow you to define shapes but that is not quite the same thing as an object.
negative
If the force moving an object points partially in the opposite direction of the object's motion, work is considered to be negative. This is because the force is acting against the direction of motion, reducing the overall work done on the object.
Determine the position of the object at two different times. The vector joining the first with the second of those positions points in the direction of the objects motion.
An infinite number of points (0-dimensional objects) can form a line (a 1-dimensional object).
You can conclude that the acceleration of the object is not constant.
Nothing will happen. Nothing will happen. I think.

L points also known as Lagragian points, Libration points and Lagrance points. the L points are the five positions in an orbital configuration where a small object affected only by gravity can theoretically be stationary relative to two larger objects (such as a satellite with respect to the Earth and Moon).
