The computer calculates the kinetic energy at each velocity measurement by using Eq. (4.1). ​ Then it makes a plot  of $\delta PE$ vs $KE$. What do you expect the slope of this graph to be?  Are your results consistent with this expectation? ​ Answer these questions in the appropriate place on your worksheet.  ​ The computer calculates the kinetic energy at each velocity measurement by using Eq.

-It also makes a second plot, one of velocity vs. time. The slope of this graph is, of course, the acceleration. ​ Check whether the value of acceleration matches the value you expect from Eq. (4.4). ​ Answer the relevant questions in the appropriate place on your worksheet. ​  +It also makes a second plot, one of velocity vs. time.
