Earth's surface is a common reference point for determining position and motion.

The earths surface, a building, and a moving object
True. Motion is always measured in relationship to a point of reference. This point of reference can be stationary or moving itself, but it is essential for determining the position, speed, and direction of an object in motion.
There are various ways to determine motion. The common way is having a reference point and the change from that position is what will determine the motion.
motion occurs when an object changes its position relative to a reference point.
An observer uses a frame of reference to detect motion because motion is relative and depends on the observer's point of view. By using a frame of reference, the observer can establish a stationary point against which to measure an object's position and velocity. This helps in determining whether an object is in motion or at rest relative to the observer.
Both motion reference point and displacement are related to the position of an object. The motion reference point is the stationary point from which the motion of an object is described, while displacement is the change in position of an object relative to its initial position. Both concepts help to describe the motion of an object in a specific frame of reference.

The object is in motion relative to the reference point.
The object that serves as the reference point for determining motion is known as the frame of reference. It is used to describe the motion of an object relative to another object or observer. The choice of frame of reference can affect how motion is described and analyzed.
