Physics

The area under a velocity - time graph represents displacement.

To understand this, consider a simple case where the velocity is constant. If an object has a constant velocity v over a time interval , the displacement . In a velocity - time graph, the area of the rectangle formed (with height v and base ) gives the displacement.

For a non - constant velocity, we can divide the time interval into small sub - intervals such that the velocity is approximately constant in each sub - interval. The sum of the areas of these small regions (which is the total area under the graph) gives the displacement.

Option A, Acceleration:

Acceleration is the rate of...
