Express your answer in meters per second. ? Hint 1. Definition and graphical interpretation of average velocity. I have the velocity vs. time graph already, I just need to change it to position vs. time.Just in case you are not taking a calculus level class, the position can be deterimined by the area under the curve of the velocity graph up to the time in question. Similarly, the acceleration-time graph is said to be derived from the velocity-time graph. The various graphical representations of motion are related through the slopes of each graph.Physics Classroom: Describing Motion with Position vs. Time Graphs. For any position vs. time graph, the velocity at time t is equal to the slope of the line at t. In a graph made up of straight lines, like the one above, we can easilyCalculating the ants average velocity during this time interval is a simple matter of dividing rise by run, as weve learned in math class. Consider the position vs time graph below that represents the motion of two bicyclists.5. What is happening at the intersection of lines A and B? Determine the average velocity of the objects in the following position vs time graphs. Thus average velocity 13.33 m/s D) change in position -40 meters, time interval 3 seconds. Thus average velocity -13.33 m/s E) The object returned to its origin, thus there was no change in position. No change in position means average velocity is zero. Find the average velocity of the car whose position is graphed in Figure 2. Strategy. The slope of a graph of x vs. t is average velocity, since slope equals rise over run.Sketch graphs of: (a) position vs. time and (b) acceleration vs. time for this trip.
