Lab Seven: Conservation of Energy Purpose: In this lab, our goals are to experimentally verify the conservation of energy in a free-falling object and a mass oscillating on a spring and to observe the change of energy from one form to another. Data and Calculations : Mass of Kickball .621kg Position (meters) Mass (kg) Weight (Newtons) .111 .005 .04905 .163 .055 .53955 .218 .100 1.0300 .274 .150 1.520 .325 .200 2.00105 .380 .250 2.50155 Weight = mass (kg) x gravity (9.81m/s 2 ) Spring Constant ( k ) .927 N/m Total Mass 201.1 grams Mass of Spring 20.4 grams Results: In this experiment, we felt that the data collected was clear and concrete evidence to accomplish what we are looking to do in this lab. For the second part of the experiment, we found the spring constant using the lengths traveled by the spring when using varied weights (see above). Using the equation mass x gravity, we were able to find the weight of each oscillating mass. Conclusion:
