### Physics & Controls
Here's how the simulation brings the ball's motion to life, along with the controls you can use.
- **Gravity & air drag:** The ball continuously accelerates downward while air resistance gradually slows its velocity, creating a natural falling and drifting feel.
- **Wall collisions:** Each wall checks the ball's distance and, if overlapping, pushes it out while reflecting velocity based on restitution and tangential friction. The wall's rotational velocity is also factored in, so bounces feel realistic.
- **Rotating hexagon:** The container spins at a constant angular speed, and collisions are resolved against the moving wall segments.
- **Controls:** The **Pause/Resume** button toggles simulation, **Reset** restarts with a random initial position and velocity. Keyboard shortcuts are **Space** for pause and **R** for reset.
- **Visual feedback:** A glowing hexagon, motion trail, and gradient ball help you follow the physics.

**Optimization Tip:** You can adjust constants like `GRAVITY`, `RESTITUTION`, `WALL_FRICTION`, and `OMEGA` at the top of the script to change how bouncy, heavy, or fast the ball behaves.
