Velocity-time graph for an object that begins accelerating, then moves at a constant speed before finally decelerating, StudySmarter originals. GCSE Speed, velocity and acceleration Average speed is distance divided by time. The area beneath the acceleration graph is marked as the change in velocity within a specified interval of time. The same will be negative if V2<V1, that is if the velocity of the object decreases with time. A velocity vs time graph allows us to determine the velocity of a particle at any moment. After 20 seconds, it stops accelerating and sustains a uniform velocity that is v = 25 m.s-1. If you have two of these variables, you can always solve for the third. Constant speed is shown by a horizontal line. When looking at an acceleration-time graph, you can determine the velocity of the object as the area under the acceleration curve is the change in velocity.
