There are 54% of student's mental models influenced by another factor, such as logical resoaning ang teacher's explanation. Hukum newton ada 3 yaitu: Hukum newton I Hukum newton II Hukum newton III NEXT. Demikain materi terkait Humum Newton 1 2 3 yang dapat disampaikan semoga bermanfaat.
Hukum II newton ‘ percepatan sebuah benda berbanding lurus dengan besarnya gaya yang bekerja pada benda dan berbanding terbalik dengan massa benda tersebut’. Student's mental models influenced by experiment with 10%, student even see the same case 6% and 30% is learning from physics book. Dinamika berkaitan dengan hukum newton dan Gaya gesek. f 20 N (arah ke kiri) Kesimpulan jawaban : Nilai f adalah 20 N arah ke kiri perhatikan gambar berikut. Hukum I newton ‘Sebuah benda akan tetap bergerak dengan kelajuan konstan kecuali jika pada benda bekerja gaya yang tidak seimbang. The students have Newtonian model with 18%, the most student used Hybrid model with 24%,Ariestotelian model with 11% and another model with 47%. The results found that students have three determined mental models. Hukum Newton II berbunyi, Percepatan yang dihasilkan oleh resultan gaya yang bekerja pada suatu benda berbanding lurus dengan resultan gaya, dan berbanding terbalik dengan massa benda. In addition, interview holded for confirm the student's answers. The questionnaire used to identificate the factors that possed the student's mental models. Two tier multiple choice diagnostic test used to find coceptual understanding (step I) and identificate the student's mental models (step II).
This study used test and non-test methods. This sample selected 101 students by purposive sampling technique. Jenis gaya Alat ukur Resultan gaya I II III Newton ini menyatakan. The population of this research are students of X grade at State Senior High School 5 Yogyakarta, 243 students. Gerak Lurus Berubah Beraturan Gerak benda dengan lintasan lurus dan percepatannya tetap.
This study are aimed to identificate student's mental models of Newton's Law of Motion and its factors that possed for X grade at State Senior High School 5 Yogyakarta.
