Objectives
The objective of this lab experiment was to determine the spring constant k by stretching
the spring and applying Hooke’s Law. By doing this we would be able to verify that
period of vibration of a body on a spring is independent of the amplitude. We also
measured the period T of a simple pendulum as a function of the length L of the
pendulum.
