A speedometer is an instrument used to determine if something is in motion by measuring its speed or velocity. The speedometer indicates how fast an object is moving in relation to a fixed point or reference frame.
A reference point is a place or object used in comparison to determine if an object is in motion. It serves as a frame of reference to establish the motion of an object relative to a fixed point.
An accelerometer is an object that measures acceleration, which can be used to determine motion. It detects changes in speed or direction of an object and provides data that can be used to track its movement.
A reference point is a fixed object used to determine the movement of another object. It serves as a stationary position against which motion or change can be measured or tracked.
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.
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.

That would be a reference point.

A reference point is used as a comparison to determine if an object is in motion. This reference point can be a stationary object or a specific location that helps observers detect movement in relation to it.
The phrase usually used for this is "reference frame".
