Pressumably, some reference point must be used - for example, two distant stars or galaxies, the Sun and a distant star, etc.
On the Earth the directions are relative to the surface of the earth. EG noth south etc etc. The speed too is relative. Once you leave the relativity of the Earth, the directions North , south etc become un usable. There would be no Gyroscopic compass. So The space map is to be imagined in 3D. Once you leave the earth's gravity you are pretty much on your own. on the Space map of 3D the transit line show directions. .....
This is pretty much my imagination .
Longitudinal waves are compressional waves which means they travel in one direction and do not radiate out. They are created by continuous intermittent compression and thus will have sparse spacing and then compressed and then sparse, compressed and so on. Such wave requires a medium such as solid liquid or air to travel thru. They cannot travel thru space.
Yes. No air friction.
Sound waves are LONGITUDINAL. This means the direction of the particles is the same as the direction of the wave. Sound waves are a series of compressions (areas of high density) and rarefactions (areas of low pressure). All sound waves are caused by vibrations. They only travel if there is a medium for them to travel along, therefore there is no sound in space, or in a vacuum as it cannot travel.
sound cannot travel through empty space.
Any electromagnetic wave can travel through space, and they all do.
In 3 dimensional space, there are 12 coordinates, although 9 will be enough to determine the rest..
It is the difference between the coordinates of two points in 2-dimensional space, measured in the horizontal direction.
The coordinate plane in 2-dimensional space has one point which is the origin. This point is usually denoted by the letter O and has coordinates (0, 0). There are usually two mutually perpendicular axes - one horizontal and one vertical. The first coordinate of any point is the distance of the point, in the horizontal direction, from the vertical axis. The second is its distance, in the vertical direction, from the horizontal axis. In space with 3 or more dimensions the coordinates are defined in an analogous manner.
If a few trillion atoms of exhaust are shot in one direction into the vacuum of space the rest of the ship wll move in the opposite direction with the same momentum. These are called burns.
It is the direction the radar is facing. It allows the radar to determine where the object is located in 2D or 3D space.
The coordinate n-space usually consists of n mutually perpendicular axis which all meet at a point called the origin. The coordinates of any point are the distances of the point along the directions of each of these axes, in order. In 2-dimensional space, for example, there are two axes which are conventionally called the x and y axis. The x-axis is horizontal and the y-axis is vertical. The coordinates of any point are the ordered pair consisting of the distance of the point from the origin in the horizontal direction and the vertical direction. In 3-dimensional space, there are 3 axes, and so on.
the coordinates are for finding planets in space
A shot in to space but- Maybe they have a 3 dimensional map with the coordinates of the planets and they're moons already in the system. i think it would look like a 3D Nautical Star.
The coordinates are X-56, Y-52.
counter to the earth's rotation Exactly wrong..........it travels WITH the Earths rotation.....eastwards
Rockets are convenient for space travel. Aircraft use the air to hold them up, but spacecraft travel beyond the Earth's atmosphere.
We travel by a space rocket!
