Physics I am totally lost. Graphs and Relationships This activity will help you meet these educational goals:  use real-world data captured on video, make observations, analyze data, and communicate your results in written form  use mathematical processes and analysis in scientific investigation to analyze real-world situations  employ online tools for research and analysis Directions Read the instructions for this self-checked activity.Type in your response to each question, and check your answers.At the end of the activity, write a brief evaluation of your work. Activity In this activity, you will connect the use of graphs to real-world data and situations.As you will see, you can often describereal-worldsituations fairly accurately with one of the types of graphs that you have seen in the lesson so far. Question 1:Car Zoom In this activity, you will examine the horizontal displacement and velocity of a car using Tracker, a free scientific tool available through the Open Source Physics Project. To begin your investigation, open the TrackerCar Zoomexperiment.Click play () to watch the movie.The other video controls allow you to rewind () the video or step forward () or backward () one frame at a time. Part A Based on what you saw, how would you describe the car's velocity?Discuss both its speed and its direction.Mention any change to speed or direction you observe. Part B For this car, predict the shape of a graph that shows distance (x) versus time (t).Note that time is the independent variable and will be on the bottom axis.  Part C Check your graph prediction.In Frame 4, click the view icon and select Plot View.You may click on any graph point to see thetandxvalues displayed.(Clicking a graph point also jumps the video to the frame for that data and highlights data for that point in any data tables.) How does the graph compare with your prediction?  Part D Now predict the shape of a graph that shows velocity in thexdirection (vx) versus time (t).  Part E Change the display in Frame 3 to a graph to check your prediction.Click graph points to make quantitative observations of any notable points or data changes.Describe how your prediction and the graph compare. Part F Use the data from the table to calculate the average velocity for the car to one decimal place.(UsePart F Use the data from the table to calculate the average velocity for the car to one decimal place.(UseVx=xt.)  Question 2:Start-Up Now you will use another Tracker experiment to examine the displacement, velocity, and acceleration of a car in thex(horizontal) direction.To begin your investigation, open the TrackerCar Start-upexperiment. Part A Play () the video.At the end, rewind () and step forward () one frame at a time to observe the step-by-step changes in position.Based on your observations, describe the car's displacement (distance and direction from the starting place) over time. Part B Run the video frame-by-frame again.Now describe the car's velocity (speed and direction) over time. Part C Based on your descriptions above, predict the shape of the displacement versus time graph and the velocity versus time graph.Explain your reasoning. Part D Test your predictions by changing the displays in Frames 4 and 3 to graphs.(Click the view icon in the upper left of each frame and select Plot View.) How good were your predictions?Were there any surprises? Part E What type of graph is the displacement versus time (xvs.t) graph?What is the mathematical relationship betweenxandt?  Part F Based on what you see with the velocity graph, describe the acceleration over time. Part G To check your prediction, change thexvs.tgraph to an acceleration versus time graph.(Click thexlabel on the vertical axis, and chooseax:accelerationx-component.) How well does your description match this graph?
