1. Two particles are displayed on a canvas, represented by circles.
2. Four sliders control the system’s properties:
   • Mass of Particle 1 (1 to 10 kg)
   • Mass of Particle 2 (1 to 10 kg)
   • Position of Particle 1 (0 to 600 on the x-axis)
   • Position of Particle 2 (0 to 600 on the x-axis)
3. The particles’ masses and positions are displayed below their respective sliders.
4. The calculated Center of Mass is shown at the bottom of the game.

The game continuously updates to show:

• The particles’ positions and sizes (size represents mass) on the screen.
• A green vertical dashed line indicating the position of the center of mass.
• Real-time changes in mass and position as the sliders are adjusted.
• Instant calculation and display of the Center of Mass based on the current masses and positions.

Key learning aspects of this game:

1. Visual representation of how particle masses affect the center of mass.
2. Demonstration of how particle positions influence the center of mass.
3. Real-time calculation of the center of mass using the formula: (m1x1 + m2x2) / (m1 + m2).
4. Interactive experimentation with different mass and position combinations.
