The position-time graph shows the motion of the particle (car). The smooth curve is an approximation as to what happened between the data points. The average velocity is rate (w.r.t. time). velocity without analyzing a position-time graph. Reading Check Give the equation for average velocity. Example: A sprinter takes 8.2 s to run forward 75.0 m. What is the sprinters average velocity? In mechanics, the derivative of the position vs. time graph of an object is equal to the velocity of the object. In the International System of Units, the position of the moving object is measured in meters relative to the origin, while the time is measured in seconds. Figure 2.15 shows such a graph for the race car from Figure 2.13. Notice that now we are plotting velocity versus time, not position versus time as before.
The average acceleration between any two points on a graph of velocity versus time equals the slope of a line connecting those points. 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. If the time velocity graph is a straight line, acceleration remains constant.The ticker tape can be cut into strips of equal time (equal number of ticks) and pasted together to form a chart for analysing the motion ofFigure 2.10 shows the ticker tape produced.

Locate the time and position where the instantaneous velocity approximately equals the average velocity for the entire run that you calculated in Question 2. Is it at the middle position between the first and last9. Use your data table for position and time to create a position vs. time graph in Excel. Fig. 3.16 Position-time graphs of two objects with equal velocities.On an x-t graph, the average velocity over a time interval is the slope of the line. connecting the initial and final positions corresponding to that interval. Lets look at another example. Figure 2.13 shows a graph of position versus time for a jet-powered car on a very flat dry lake bed in Nevada.Strategy. The slope of a graph of d vs. t is average velocity, since slope equals rise over run. 2.7. 29. If the average velocity of an object is the same for all time intervals, then the object moves at a(n) . A. constant velocity B. relative speed C. increasing acceleration D. changingAlso, knowing that any acceleration on a position vs. time graph shows a parabola, (C) is the correct answer.
