This app is aimed at students who are looking for exercises on the law of gravitation with detailed solutions.There are tasks, tips and solutions on the following topics:- Keplers laws- Gravitational force and mass determination of planets- Lifting work in the earths gravitational field- Gravitational Potential- Gravitational field and Abaric point- rocket physicsWith each processing, there are always new values in the tasks, so that it is worth repeating the task.For each task, tips and a theoretical part help with the processing. After a result has been entered, it is checked. If it is correct, points are awarded based on the level of difficulty. A sample solution can then also be viewed.If the result obtained is incorrect, it is recommended to repeat the task.
