Lab Practicum Report Abstract The experiment hoped to show how the potential energy of an elastic cord changed as it was stretched. With a 30 cm cord, an air track, glider, 2-picket fence, and photogate, the velocity was measured at six succeeding 10 cm intervals, starting at its relaxed position. Three trials were taken for each point. It was noted that the elastic cord had similar properties to a spring, as the velocities increased proportionally, with no discernable acceleration. Using the conservation of kinetic energy, it was deduced that the kinetic energy equaled potential energy, so the formula of kinetic energy equals one half mass times velocity squared. The results matched up with the formula and the data was definitely enough to reinforce the model set up. Introduction The group had the task of finding how the potential energy of an elastic cord changes as it is stretched. The results needed to be properly quantified like a normal lab report.
