Does reference point depend on direction?
i don't think it does because reference point is a point with other points and lines connected to it so it doesn't depend on direction
What are Reference points to explain that train is moving?
A person standing on the ground. For the person on the train, ground is moving and the train is stationary.
Direction and velocity are what to a frame of reference?
Frame of reference is related to motion because reference points enable us to see that an object is moving. ======================== Motion is related to a frame of reference because there is no such thing as 'real' motion or 'real' rest. 'Rest' and 'motion' are always with reference to something else. The book that you are reading is at rest with reference to your lap, your lap is at rest with reference to the seat you're sitting in, and you, the book, and the seat are all at rest with reference to the airplane you're flying in at 400 miles per hour. See what I mean ?
Why reference points that are stationary are usually chosen to determine whether an object is in motion?
To support you in specifying how the reference point is placed and how the object is moved away from the reference point.
What type of object other than unmoving objects can be used as reference points?
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.
How important are the reference points in a coordinate system?
If the reference points are not correct, the location of any coordinate will be incorrect.
What are useful reference points?
Reference points are used in order to easily access information that is in a larger collection of data.
what Navigation at sea requires the use of many points and lines to reference location and trajectory.What are the minimum points of reference needed to determine a trajectory (line)?
2 points
What is the Distributor points gap?
.016 as a reference
A number line used to reference points?
An axis.

What are the importants of the microscope?

Why are words are importants?
yes
What are the two basic points of reference on the surface of the earth?
which are two basic point of reference on the surface of the earth
Why do reference points that are stationary are chosen to determine whether an object is in motion?
To help you state how the reference point placement is and how the object is moved from the reference point
What are fixed reference points in engineering drawings?
FIxed reference points refers to a coordinate system or set of axes within which measure the position, orientation and other properties of an object in the drawing.
How is an exact position in space identified?
There are several methods.You need a reference point (the origin. For an n-dimensional space you will need a set of n axes and n measures which define the position with regard to origin. The axes need not be orthogonal (at right angles) as can be seen from isometric graph paper. The measures need not all be distances, they can comprise one distance and the remainder being angles.Alternatively, you can have many reference points and directions from these reference points to the position. This is the system used by early cartographers for making maps before satellite mapping became possible. The reference points were called triangulation points, and as they moved across the region being mapped, they identified new triangulation points (whose positions they had worked out) so that they had these reference points reasonably near the position to be identified.Yet another method was to have a set of reference points and distances from these reference points to the position. This is the system used for GPS where the reference points are 3 or more satellites and the measures are distances to the position. Actually, the measures are of time but given the speed of light in the Earth's atmosphere, converting time to distance is trivial. A lot of trigonometry follows.
