I Dont know thats why im asking it!!
It's important to know that you reference point is moving because if an object is in motion and if it changes position it is relevant to a reference point.
If your reference point it moving, then it cannot be considered a reference point. Your reference point should be something constant. Something that can be relative to any situation. If it moves, you lose this relativity.
Knowing if your reference point is moving is important because it affects our understanding of motion and helps us accurately describe and predict the motion of objects in relation to that reference point. It allows us to distinguish between the motion of the reference point and the motion of the object being observed. Additionally, understanding the motion of the reference point is crucial for correctly interpreting data and making informed decisions in fields such as physics, engineering, and navigation.
An object is moving in relation to a reference point if its position changes with respect to that point over time. By observing the object's changing position relative to the reference point, we can determine whether it is in motion.
A reference point is part of the definition of movement or displacement. The difference, over time, of your distance or orientation to a given reference point or points defines movement.

I know this because it was on my exam and i got the question right. Answer- A reference point.
To determine velocity, you need to know the object's speed (how fast it is moving), the direction in which it is moving (velocity is a vector quantity with magnitude and direction), and the reference point or frame of reference from which the velocity is being measured.
It depends on your reference point. You are moving when you move farther away from one reference point and closer to another. So an example of this could be that the floor is one reference point, and the ceiling is another. If you jump up, you would move closer to the ceiling and farther away from the floor. If you and a friend are your reference points, and you throw a ball to your friend, the ball moved bacause it went farther from you, and closer to your friend! That is how you know an object is moving! Now, technically we are always moving... the earth is moving! So if you are thinking about it like that, then maybe the sun is one reference point, and Mars could be the other! Who knows! But it just all depends on your reference point!
A reference frame is needed to determine an object's motion because motion is relative. An object is in motion only when compared to another object or a specific frame of reference. Without a reference point, it's impossible to determine if an object is moving or stationary.
No, Einstein proved that all inertial frames are equally valid references. You don't have to assume it's "fixed in place" or even know exactly how it's moving relative to any other frame as long as you know how the measured object is moving relative to the chosen reference frame.
To identify and objects location you need three pieces of information. These are a reference point, a distance from the reference point, and a direction from the reference point.
