Which concept requires using reference points to define location?

Position is defined as the specific point in space where an object is located, and it is inherently dependent on reference points. To accurately describe the location of an object, you need a frame of reference. For example, when stating that a car is 50 meters east of a gas station, the gas station serves as the reference point that provides context for the car's location. Any statement about an object's position requires a clear reference point to indicate where the object is situated in relation to that reference.

In contrast, concepts like velocity, acceleration, and momentum, while they may involve direction and magnitude, do not center on the concept of location itself, but rather on how objects move or change their state over time. Velocity describes how quickly an object is moving and in what direction, but it builds upon the idea of position without defining it. Similarly, acceleration refers to the change in velocity, and momentum relates to the mass and velocity of an object, reflecting its motion rather than its position in space. Thus, position specifically requires reference points to define the location of an object accurately.
