What it is:
A velocity-time graph shows how the object's velocity changes over time.
Velocity itself tells you how fast the object is moving at a specific moment, but not how far it has gone.
Displacement, on the other hand, indicates the actual change in position of the object from its starting point.
The area under the graph acts like a summation of all the tiny velocity values over the time interval, essentially accounting for how far the object traveled at each instant.
Mathematically, this translates to the formula: displacement = area under the velocity-time graph.
