Distance is:

Distance is defined as the amount of space between two points, which is generally measured in a straight line. This approach allows for a clear understanding of how far apart two locations are without considering the direction of travel. It is a scalar quantity, meaning it has magnitude but no specific direction associated with it. Measuring distance in this straightforward manner provides a precise measure that can be easily interpreted.

In contrast, distance is not always a vector quantity, as vector quantities entail both magnitude and direction, while distance itself does not specify a travel direction. Additionally, stating that distance is velocity divided by time is incorrect; instead, it is the formula for calculating velocity when the distance and time are known. Finally, measuring distance in a circular path does not apply universally, as distance can be calculated in various geometrical forms, not just circular.
