This research is a research development which aims to 1) Develop a Physics game learning based on Android that is feasible to be used as a learning media on physics subjects. 2) Knowing students' responses to physics game learning based on Android as learning media 3) Knowing that physics game learning based on Android as learning media can improve students' ability to analyze in the chapter of momentum, impulse, and collision. This research uses the ADDIE development model. This research has been tested by 3 media experts and 3 material experts with the results of the assessment stating that the media is feasible to be used as a medium for physics learning. The subjects of this research were 11 students in class X of Industrial Chemistry at the Vocational School of Gula Rajawali Madiun. The results of this research development indicate that: 1) media physics game learning based on android meets the feasibility standard to be used as a learning medium on physics subjects. 2) The learning media of Physics game learning based on Android gets a very good response from students. 3) Physics game learning based on Android as learning media can improve students' analytical skills in the chapter of momentum, impulses, and collisions with an average N-Gain of 0.54 which is in the medium category.

Adalbert Wraný (*1836, †1902) was a doctor of medicine, with his primary specialization in pediatric pathology, and was also one of the founders of microscopic and chemical diagnostics. He was interested in natural sciences, chemistry, botany, paleontology and above all mineralogy. He wrote two books, one on the development of mineralogical research in Bohemia (1896), and the other on the history of industrial chemistry in Bohemia (1902). Wraný also assembled several natural science collections. During his lifetime, he gave to the National Museum large collections of rocks, a collection of cut precious stones and his library. He donated a collection of fossils to the Geological Institute of the Czech University (now Charles University). He was an inspector of the mineralogical collection of the National Museum. After his death, he bequeathed to the National Museum his collection of minerals and the rest of the gemstone collection. He donated paintings to the Prague City Museum, and other property to the Klar Institute of the Blind in Prague. The National Museum’s collection currently contains 4 325 samples of minerals, as well as 21 meteorites and several hundred cut precious stones from Wraný’s collection.
