Displacement is defined as the change in position of an object and is a vector quantity. It is the shortest distance from the initial position to the final position, taking into account the direction. When you refer to displacement during a specific unit of time, you might be talking about the concept of velocity.
Velocity is calculated as the displacement divided by the time interval during which the displacement occurs:
\[ \text{Velocity} = \frac{\text{Displacement}}{\text{Time}} \]
Thus, in this context, velocity gives you an idea of how fast the object is moving and in which direction over that specific time period.
