Amparo 2ObjectivesThe objective of this lab experiment was to determine the spring constant kby 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.
