Simple Harmonic Motion Abstract In this experiment, we were to investigate the oscillatory motion of a body under the action of a spring and compare its motion to that of a simple pendulum. By utilizing the equipment provided, we attached a spring to an apparatus with varying masses hung from the bottom and recorded the data. The data showed a 6.5% deviation between periods, a 2.2% deviation between kinetic and potential energy, and a 7.8% deviation between the total energy. Also, we performed a second experiment in order to calculate g for a mass oscillating through a photogate and compared it to the acceleration due to gravity to determine a percent deviation. The deviations ranged from 15.3% to 22.9%. Both experiments seemed to be a complete success based on the data and deviations collected. Introduction: The objective of this lab was to investigate the oscillatory motion of a body under the action of a spring and to compare its motion to that of a simple pendulum. Simple harmonic motion is the name given to the most uniform of all periodic rectilinear motions. Nearly all motion is, in some sense, periodic, e.g. from the oscillation of atoms, to the swinging of pendulums, to the meanderings of mankind, to the turning of the Earth on its axis, to the revolution of the planets about the sun, to the revolution of the sun about the Milky way, to the motion of the Milky Way in the local cluster of galaxies. If a body hangs from a spring, stretching the spring because of its weight, a slight displacement of the body from its equilibrium position produces an oscillation. If the spring is again “simple”, the oscillation is harmonic. If an additional weight is added to this simple spring, the additional stretch of the spring to a new equilibrium position caused by the weight is proportional to the weight added. The body which hangs from a spring is an easily
