Final answer:
Motion refers to the change in position of an object over time. Position describes where an object is located in relation to a frame of reference. Displacement is the change in position of an object, including both magnitude and direction.
Step-by-step explanation:
Motion refers to the change of an object's position over time. When we talk about position, it's a specific location of an object in a given frame of reference at a particular time.
Displacement is the change in position of an object, often represented as the vector quantity Δx (Δ representing 'change in') which is calculated as xf - xo (where xf is the final position and xo is the initial position).
The distance, on the other hand, is the total length of the path that an object travels while moving from one position to another, regardless of direction, making it a scalar quantity.
To understand the relationship between these concepts, consider the scenario of a person walking from their home to the store. The starting point (home) is the initial position.
If they travel directly to the store and then return home, the displacement would be zero since they return to the starting position, however, the distance traveled would be the sum of the outward and return journey lengths.
