The Influence of Inclined Plane Angle to The Oscillation Period of Spring and Block Systems

The topic of oscillation in spring and block systems in the inclined plane is fairly complex and rarely to be discussed in the oscillation research topic. Not only theoretical calculations, physical quantities in this topic can also be calculated through experiments. This research determines one of the physical quantities present in this system, namely the oscillation period experimentally with the help of a light sensor on a smartphone. Experiments were carried out with variations in angular position on the inclined plane with spring-mass block launched from the top of the plane. The spring used has a constant (2.68313 ± 0.002152) N/m while the block has a mass of 0.0892 Kg. Through weighted linear regression analysis, this study shows a linear relationship between the angular position of the inclined plane and the oscillation period with a linear equation y = -0.005x + 1.3661 and R2 = 0.98358. The greater the angle of the incline, the smaller the value of the oscillation period. These results can provide further development of the use of light sensors on smartphones for physics experiments, especially in spring systems and block on inclined planes.
