उत्तर
The slope of the speed–time graph gives acceleration.
Explanation:
Acceleration is the rate of change of velocity over time. Since speed is the magnitude of velocity, a speed-time graph essentially shows how the speed of an object changes with time. The slope of this graph, which is the change in speed divided by the change in time, thus indicates the acceleration of the object.
