The "BodyProblem" app is a real-time gravity interaction simulator. Through this app, users can create multiple objects in a virtual space and directly observe and experiment with how they respond to each other's gravity. Explore physical principles by adjusting the mass and position of each object! Key Features: Interactive Physics Simulation: Users can place objects and set their mass to experience the laws of gravity firsthand. Intuitive User Interface: With a simple and easy-to-understand interface, users can add and move objects with just one finger. Various Simulation Options: Adjust various variables such as the distance between objects, their mass, and initial velocity to change the conditions of the experiment. Visual Effects: Beautiful graphics and smooth animations visually represent the interactions of gravity. Educational Value: Understand the basic principles of physics and stimulate interest in natural phenomena.
