what is the distance betwenn two points.

derived unit, standard, displacement

The distance between two points is a line segment.

1. Units of measurement that are obtained by combining other units are called derived units. These derived units are formed by mathematical combinations of base units. For example, the unit of speed is derived by combining the units of distance and time (e.g., meters per second or kilometers per hour).

2. The exact quantity commonly used for comparison is known as a standard. In terms of measurement, a standard serves as a reference point against which other quantities can be assessed or compared. Standards are typically well-defined and widely accepted, ensuring consistency and accuracy in measurements.

3. The distance between two points can be measured using the concept of displacement. Displacement refers to the change in position from one point to another, expressed in terms of distance and direction. It represents the shortest path between the two points, often measured in units such as meters or kilometers.
