Introduction/ Abstract:

Simple harmonic motion is the study of oscillation. An object undergoes oscillation when it experiences a restoring force which restores this object to equilibrium positon. The Simple harmonic oscillation occurs when the net force on an object along the direction of motion is proportional to the object’s displacement and in the opposite direction by this equation F = -kx. In addition, an object whose position-time graph makes a sine or cosine function is in simple harmonic motion. This type of relation is called Hooke’s law. The purpose of this experiment is to prove Hooke’s law and study Simple harmonic motion and to show that this equation T = 2 is valid during Simple harmonic motion.

Theory:

The relevant theoretical concepts and equations used in this experiment are:

T = 2

| E1 − E2 |

E1 + E2

2

K=

Percent difference =

Experimental Procedure:

The Computer and sensor calibration along with equipment such as DIN plug, force sensor, rod, clamp, spring, sensor’s hook, and hanger were all set up already in the laboratory before we started doing the experiment.

Hooke’s law

a) We used a meter stick to measure the position of the

In this experiment,we applied Newton`s first law of motion. It descripes the external force as the sum of all external force applied to the object, which equals zero in equilirbium. As we have seen in the experiment, to reach equilibrium all the forces applied on an object shoud cancel each other out and total force reaches zero.Using different forces and weights we were able to reach equilibruim ineach trial of this

After finding the speed we can predict what the smallest frequency is to create a standing wave. This is known as the first harmonic which is also known as the fundamental frequency. Throughout this experiment we place different weights on the end of the string, because of this different tensions are created and the speed is calculated differently. We do this in order to examine how the different tensions of the string can create different frequencies for
