To convert a velocity/time graph to an acceleration/time graph, one must analyze the slope of the velocity graph. The acceleration is determined by the rate of change of velocity over time, which is represented by the slope. For example, if velocity increases steadily from 0 m/sec at t=0 to 4 m/sec at t=2, the slope is a constant 2 m/sec². This indicates a constant acceleration of 2 m/sec². Understanding the relationship between slope and acceleration is key to making this conversion.
