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. (4.1).

- | 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. The slope of this graph is, of course, the acceleration.
