Motion is nonzero speed, or span over time. Here within, there is net motion and gross motion, as span is directional and additive to obey the zero- identity.
Star Charts were traditionaly used in naval navigation, where the only point of reference you had to the rest of the world were the stars. You could therefore find your position by comparing the stars you see in the skies to the star charts.
There are many things that could interest a person about a quality engineer position. A quality engineer position could offer great challenges for example.
The change in an object's motion, is simply force.The object cannot change motion unless acted upon by an outside force. For example: If I throw a baseball, it will never stop unless acted upon by gravity (or the outside force). Or the outside force could be it smacking into a wall or your friends head.
Imagine that you could ride a baseball that is hit hard enough for a home run. If the baseball is your frame of reference, what does the Earth appear to do? Incorporate a diagram with your explanation.
Relative motion is movement in relation to a frame of reference.
Something that is in motion changes position, the position of the object is described relative to another object. If you chose the tree as a reference point, then the object in the pictures has been in motion because it has changed postions relative to the tree.
Motion described from a particular reference point is called relative motion. It is the concept of observing an object's movement relative to a specified frame of reference, which could be a stationary object or observer. The description of motion may vary based on different reference points chosen.
You could be moving in one frame of reference but not in another due to the concept of relative motion. Motion is always relative to a specific frame of reference, so if one frame is moving in relation to another, an object could appear to be stationary in one frame and moving in another. This is a key principle of Galilean relativity.
A tree can be used for a frame of reference for the motion of a snowboarder.

Motion is relative to your frame of reference which you can choose arbitrarily. Most people use the surface of the earth as their frame of reference or their own body depending on the calcualtion they are doing. However, that makes describing the orbits of the planets more difficult so the sun is often used as the frame of reference in that case. If I'm inside a car my frame of reference might be my head, the car or I could choose a spot along the road (the surface of the earth). From a science standpoint you should get the same answer no matter what frame of reference you arbitrarily choose but it often turns out that choosing a particular frame of reference makes certain calculations much easier. Just keep in mind that motion is always relative to something and you get to pick whatever that something is when you are solving a problem or doing a calculation. Just don't change frames of reference in the middle of a problem or your answer will likely be incorrect.
Yes. On Earth, the reference point is easy to define: it is either the ground, sky, or things. In space, it's not so easy, but we often use the Sun as a reference. Beyond the Sun, perhaps the motion of our solar system could be measured using the Milky Way galaxy as a reference.
A change in position refers to moving from one location or posture to another. This could be physical movement in space or figurative movement in terms of one's stance or perspective on a certain issue.

Yes, that is true. Motion is always measured relative to a chosen frame of reference, which could be a stationary object, observer, or a specific point in space. The choice of frame of reference can affect how motion is perceived or described.
