Java Gravity Simulation

Why It Is Useful

The project is useful as a lower-level implementation exercise: it builds simulation pieces explicitly instead of relying on a browser sketching library.

Problem It Solves

Understanding a physics engine requires more than seeing motion; the object model, vectors, and update loop need to be built and debugged.

Real-World Applications

• Game physics engine foundations.
• Simulation code that separates models from rendering.
• Java practice around classes, packages, and reusable math utilities.

Concepts Used

• Object-oriented simulation design
• Vector classes
• 2D and 3D force integration
• Time-step update loops

Solution Used

• The source separates gravity objects, vectors, handlers, and simulation entry points.
• Forces update acceleration, velocity, and position over each step.
• The structure creates reusable pieces for expanding the simulation beyond one demo.
