Abstract The purpose of this laboratory experiment is to better understand harmonic motion. With the use of a spring and various weights, we will be studying the behavior of the springs under static and dynamic situations. We will be able to determine the spring constant of each individual spring. Also we will be observing the effects of amplitude, force and mass on the spring force and oscillating periods of the various masses. From the data we are able to compile a graph, which will tell us the spring constant by using the slope value as your answer. Doing all of these procedures in lab I can see clearer now harmonic motion works along with its components, such as Hooke’s Law.
