Create a 2D simulator showing the collision of two objects on a frictionless surface. Include input fields for the mass of object 1 (1–10 kg), mass of object 2 (1–10 kg), initial velocity of object 1 (–10 to 10 m/s), and initial velocity of object 2 (–10 to 10 m/s).

Project Overview:
Develop a 2D collision simulator that demonstrates the interaction of two objects on a frictionless surface, with physics calculations and animations.

UI/UX Design and Flow:
- Include a form with input fields for mass and initial velocity for both objects.
- Allow users to switch between two collision types: elastic and inelastic through a simple toggle or dropdown.
- Animate the collision showing simple colored circles representing the objects.
- Display the velocities post-collision and a graph of momentum relative to time.
- All captions and labels in Russian.

Core Functionality and Logic:
- Implement the physics calculations for both elastic and inelastic collisions.
- Ensure the objects' post-collision velocities are calculated and displayed.
- Animate the impact showing the change in velocities and momentum.

Best Practices:
- Use clear, intuitive controls for switching collision types and inputting object properties.
- Optimize animations for smooth rendering across different devices.
- Ensure text localization is consistent for a Russian-speaking audience.

Additional Details:
- Provide a FAQ section explaining the user experience when switching between collision types: Elastic shows separate post-collision velocities; inelastic shows shared velocity.
- Ensure the design is user-friendly and visually informative, supporting an engaging learning experience.

Design a 2D simulator showing collision of two objects moving toward each other on a frictionless surface. Include a form with input fields for mass of object 1 (1–10 kg), mass of object 2 (1–10 kg), initial velocity of object 1 (–10 to 10 m/s), and initial velocity of object 2 (–10 to 10 m/s). Display the velocities after collision and animate the impact.

Q: What should the user experience be when switching between collision types?
A: First option: totally elastic collision. Second option: inelastic collision, objects share same velocity

Q: How should the objects be visually represented during the simulation?
A: Simple circles with different colors for each object.
