Three examples of reference points that are stationary relative to Earth include the North Star (Polaris), which provides a fixed point in the sky for navigation; the geographic poles (North and South Poles), which are fixed locations on the Earth's surface; and a specific point on the Earth's surface, such as a landmark or building, which remains in the same location over time. These reference points help in measuring movement and position relative to the Earth.

What are reference points and how are they used in navigation or mapping?
Reference points are specific, easily identifiable locations or landmarks used as a basis for navigation or mapping. They help individuals determine their position relative to these points, whether in physical space or on a map. In navigation, reference points can be natural features like mountains or rivers, or man-made structures such as buildings and signs. By using these points, navigators can accurately calculate distances, directions, and routes.
Is a fixed location in space?
A fixed location in space is a point in the three-dimensional coordinate system that remains constant and does not change its position relative to other points. It serves as a reference or anchor point for measuring distances and positions within a specific frame of reference.
What type of measurement uses stars as a point of reference?
Astronomical measurement uses stars as a point of reference. By measuring the position of stars relative to each other or to points on the celestial sphere, astronomers can determine distances, locations, and other important parameters in the universe.
How compass navigate the earth?
A compass works by aligning with the Earth's magnetic field. The needle inside the compass is magnetized and points toward the Earth's magnetic north pole. By using this reference point, travelers can determine their direction relative to the north.

Motion movement and changes
Explain why reference points that are stationary are usually chosen to determine whether an object is in motion?
Stationary reference points are chosen to determine motion because they provide a consistent and fixed frame of reference. By using stationary reference points, it is easier to identify when an object is moving relative to its surroundings. This helps in accurately measuring the speed and direction of the object's motion.
What are examples of reference points?
A reference point is anything that is stationary. So, if you are on a train you know you have left the station because you moved away from the platform. Hence the platform was stationary.
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.
Why are reference points that are stationary are usually choosen to determine whether an object is un motion?
Stationary reference points are chosen to determine an object's motion because they provide a frame of reference that is not moving and can be used as a benchmark for measuring the object's motion relative to it. This helps in accurately defining the object's position, speed, and direction of motion.
Why are reference points important when measuring speed?
Reference points are important when measuring speed because they provide a stationary frame of reference to compare the movement of an object. Without a reference point, it is difficult to determine if an object is moving or at what speed it is moving. By having reference points, we can accurately measure an object's speed relative to its surroundings.
What is motion described from a particular reference point is?
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.
What are 3 examples of reference points that are stationary realative to earth?
Geographic North Pole Fixed stars in the night sky Earth's equator
What are example of 3 reference points that are stationary relative to Earth?
North Pole, South Pole, and the zero-zero point (where the equator passes through the Greenwhich Meridian.)
How do we use reference points to determine whether motion has occurred?
Reference points are used to determine motion by comparing the position of an object relative to those points over time. If the object changes its position relative to the reference points, then motion has occurred. By observing the changes in the object's position relative to fixed points, we can determine its motion, speed, and direction.
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
Why does motion occurs?
motion occurs when an object changes its position relative to a reference point.
