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.

Abstract

Penelitian ini bertujuan untuk mengembangkan Lembar Kerja Mahasiswa (LKM) berbasis Tracker Video Analysis pada materi koefisien gesek yang valid dan praktis digunakan dalam pembelajaran fisika dasar. Penelitian ini merupakan penelitian pengembangan dengan mengadaptasi model 4D yang meliputi tahap define, design, develop, dan disseminate. Subjek uji coba terbatas terdiri dari 9 mahasiswa pendidikan fisika. Instrumen yang digunakan meliputi lembar validasi ahli dan angket respons mahasiswa. Data dianalisis menggunakan persentase deskriptif. Hasil penelitian menunjukkan bahwa LKM yang dikembangkan memperoleh nilai validitas sebesar 95% dengan kategori sangat valid. Sementara itu, hasil uji kepraktisan menunjukkan nilai rata-rata sebesar 82% dengan kategori sangat praktis. Hasil tersebut menunjukkan bahwa LKM berbasis Tracker Video Analysis layak digunakan sebagai media pembelajaran untuk membantu mahasiswa memahami konsep koefisien gesek melalui kegiatan praktikum berbasis analisis video.
