Physics Labs with Computers, Vol. 1Student WorkbookP04: Position, Velocity and Acceleration Graphs 012-07000A2. Select the curve fit.• In DataStudio, click the ‘Fit’ menu button ( ). Select ‘Linear’.• In ScienceWorkshop click the ‘Statistics’ button to open the Statistics area on the right sideof the Graph. In the Statistics area, click the Statistics Menu button ( ). Select CurveFit, Linear Fit from the Statistics Menu.3. Locate the corresponding velocity value in the velocity vs. time graph.• In DataStudio, select the velocity window. Click the ‘Smart Tool’ button ( ) and movethe Smart Tool to the velocity data point.• In ScienceWorkshop, click the ‘Smart Cursor’ ( ) and move the Smart Cursor to thevelocity data point.4. Record the slope and the velocity value in the Lab Report Section.At what point in time did the average velocity occur? How does this time correspond to the timesfrom the two points selected in the position vs. time plot? Record your answers in the Lab Reportsection.5. Click anywhere in the position vs. time Graph window to deselect the highlighted points.Click the ‘Autoscale’ button to automatically rescale the Graph axes to display all of thedata. Select a polynomial fit to the position vs. time plot. If your initial data is erratic, youmay need to zoom in and select a region of the plot that is smooth.• Record the coefficients of the fit and answer the questions in the Lab Report section.6. Click anywhere in the velocity vs. time graph window to deselect the highlighted points.Click the ‘Autoscale’ button to automatically rescale the Graph axes to display all of thedata. Select a linear fit to the velocity vs. time plot. If your initial data is erratic, you mayneed to zoom in and select a region of the plot that is smooth.• Record the coefficients of the fit and answer the questions in the Lab Report section.7. Click anywhere in the acceleration vs. time Graph window. Apply a linear fit to theacceleration vs. time plot.• Record the coefficients of the fit and answer the questions in the Lab Report section.Why is the acceleration vs. time plot so much “noisier” than the other plots? Record your answerin the Lab Report section.Record your results and answer the questions in the Lab Reportsection.p. 24 ©1999 PASCO scientific P04
Name _____________________ Class ______________ Date _________Lab Report - Activity P04: Position, Velocity and Acceleration GraphsWhat Do You Think?The purpose of this activity is to study the relationship among position, velocity, and accelerationin linear motion. How do the distance vs. time, velocity vs. time, and acceleration vs. time graphsfor a fan cart uniformly accelerating, from rest, compare with one another?Prediction: Sketch a prediction of the position, velocity, and acceleration vs. time graphs forthe Fan Cart’s motion.x v at t tData TableItemResultSlope of Position vs. Time dataVelocity ValuePolynomial Equation of fit for Position vs. TimeLinear Equation of fit for Velocity vs. TimeLinear Equation of fit for Acceleration vs. TimeQuestions1. At what point in time did the average velocity occur? How does this time correspond to thetimes from the two points selected in the position vs. time plot?2. What are the appropriate units for the slopes of the position and velocity vs. time plots?P04 ©1999 PASCO scientific p. 25
