Simple Harmonic Motion

Lab Partners:


INTRODUCTION
The lab experiment investigates the motion of a visual modality on a spring as an example of simplistic harmonic Motion. Other examples are pendulums, the stars pattern of reoccurrence in astrology, or the vibration of air molecules during the transmission of sound waves.

THEORY
Simple Harmonic Motion is periodic (repeating itself in equal intervals of time) and oscillatory (back and fore over the same path). Such as the orbit of realm around the sun.
SHM occurs when a force acts in the direction opposite of the displacement of the body from its equilibrium position.
Force
Displacement
Equilibrium

The period (time interval) of SHM is independent of the bounteousness of the motion (displacement of the body or plentitude).

EQUIPMENT AND PROCEDURES
Spiral spring mount on laboratory support containing metric ruler, slotted weights, weight hanger, tour watch, and triple beam balance.
PROCEDURE I:
A whorled spring is mounted on a laboratory support. To running game the affect of amplitude on the period of vibration, four incompatible displacements are timed for 50 complete vibrations of a blow gram mass suspended on the spring.

Procedure I: Suspending 100g for 50 vibrations at varying amplitudes.|
TRIAL| AMPLITUDE| season FOR 50 VIBRATIONS (t)| PERIOD T = t50|
1| 5 cm| 41.7 s| 0.



834 s/vibration|
2| 10 cm| 41.8 s| 0.836 s/vibration|
3| 15 cm| 41.9 s| 0.838 s/vibration|
4| 20 cm| 42.4 s| 0.848 s/vibration|

PROCEDURE II:
The springs mass (MSPR), measured using a triple beam balance, was 172.4 grams. triad different masses were suspended at the end of the spring. distributively mass was allowed to reach equilibrium before applying a 10cm displacement. all(prenominal) was timed for 50 full vibrations.

Procedure II: Suspending varying masses with constant amplitude of 10 cm.|
