Part 2. Limits imposed by energy. The pendulum can be described as having both kinetic and potential energy. When the motion of the pendulum is started by releasing it from an elevated position, its kinetic energy is zero. The value of the potential energy is set by the initial height. After it is released, the pendulum swings through the bottom of its path and then raises up to a point at which it turns around and falls again. Because of conservation of energy, at the end of one swing the pendulum reaches, in the absence of drag or friction, the same initial elevation. Friction might reduce the energy, which implies the second height can be a bit lower, but never higher. Test this prediction. Using one of the string lengths from the previous part, select an initial height and let the pendulum swing, mark at both ends of the swing motion the heights you observe. Measure the height of the marks. Repeat the procedure starting from a different initial height. The prediction, of course, is still the same. Required results from part 2. o A set of values for all the sequence of heights observed. A simple statement regarding the validity of the prediction. 0 Pictures of your setup
