Abstract

Viskositas merupakan kekentalan suatu fluida atau zat cair yang diakibatkan adanya gaya gesekan antar molekul yang menyusun fluida. Tujuan dari penelitian ini yaitu untuk menganalisis kecepatan jatuh benda terhadap viskositas. Metode yang digunakan adalah metode eksperimen sederhana serta menggunakan teknik pengukuran manual yang tidak terlalu rumit. Berdasarkan penelitian yang dilakukan menghasilkan data yaitu pada air jernih kecepatan benda jatuh 0,242 m/s dan nilai viskositas sebesar 0,544 N.m/s2. Pada air keruh kecepatan benda jatuh 0,186 m/s dan nilai viskositas sebesar 0,708 N.m/s2. Pada minyak baru kecepatan benda jatuh 0,134 m/s dan nilai viskositas sebesar 0,984 N.m/s2. Sedangkan pada minyak curah kecepatan benda jatuh 0,197 m/s dan nilai viskositas sebesar 0,669 N.m/s2. Pada oli baru kecepatan benda jatuh 0,138 m/s dan nilai viskositas sebesar 0,955 N.m/s2. Dan pada oli bekas kecepatan benda jatuh 0,212 m/s dan nilai viskositas sebesar 0,622 N.m/s2. Sehingga diperoleh hubungan kecepatan dengan nilai viskositas adalah berbanding terbalik.

Abstract

The Pythagorean theorem is a fundamental concept in mathematics that is often used to solve various geometric problems. In physics studies, especially in relativistic momentum analysis, the application of this theorem can be a fast and effective solution. This article explores the application of the Pythagorean theorem in the context of relativistic momentum, where the speed and energy of objects approach the speed of light. By exploiting the quadratic relationship between the components of the relativistic momentum and energy vectors, the Pythagorean theorem allows for simpler and more efficient calculations. This research identifies the relationship between the Pythagorean theorem equation and the relativistic momentum equation through several steps. The first step involves calculating the Pythagorean theorem equation. The second step is to calculate Einstein's special relativity equations. The final step is to analyze the relationship between the two equations. In this case, the relativistic and Pythagorean momentum equations have similarities and one of the formulas can be used.
