84 Now make the force versus position graph active (click in its window). Under Analyze , select Integral to find the work done by your pull as you raised the block. Work of pull = ± What are the initial and final kinetic energies of the block in the experiment? The Work-Kinetic Energy Theorum states that: Net work done = Final KE – Initial KE Is this verified by your experiment, within the uncertainties? Explain: Going further (if time) 1 Modify the position vs time graph so that it shows both position and velocity as functions of time. a. Explain how the shape of the velocity curve is related to the shape of the position curve. b. Integrate velocity over time. What is the result? How is it related to your experimental measurements? 2 Modify the force vs time graph so that it shows both force and acceleration as functions of time. a. Explain how the shape of the acceleration curve is related to the shape of the force curve.
