A change in the position of an object is called a displacement. Velocity is the measure of the rate of change of displacement with respect to time.
That is called a distance. Common units for distance (as well as length) include the meter, the millimeter, and the kilometer.
Velocity
Speed (ex: meters/second, miles/hour)

the displacement is zero because even though she moved she went back to the same place so there is no distance between the beginning point of her walk and the end point of her walk. 0 displacement
A reference point.
The mouth is the starting point of the digestive system. When we chew our salivary glands release the enzyme amylase to start breaking down simple sugars.
(0,0,0,0)
A question.
Distance
I believe your asking for the term reffering to an objects change in position from its starting point. That term is displacement.

It should be moved 4 places.
Look at the metric ruler pictured. Assuming that 0 is visible on the measure and is also the starting point, what is the distance to point D?
both measure temperature and are based on a starting point and all have a common point(0)
Let's say we want to measure the distance between objects A and B. First, we measure the distance from the Earth(point E) to these objects(using Doppler-shifts).Then, we measure the angle AEB.We now know the lengths of two sides, and the angle between them. That's how we find the distance AB.
Yes it is. It is the starting point to measure degrees East or West.
So you have a starting point to measure by.
grravity or some other force moves it
Measure they key, typically found near one of the corners. And then measure it and see how many kilometers/miles it is then measure the distance from your starting point to finishing point and compare it to the key
