This is a web-based physics simulator that visualizes projectile motion under various conditions.
Built with HTML, CSS, JavaScript (Plotly.js) and a Python (Flask) backend, it helps users explore real-time trajectories, velocity vectors, and motion parameters.
- Dynamic Simulation: Visualizes projectile motion in real-time.
- Velocity Vectors: Displays directional arrows along the path.
- Height Gradient: Trajectory path changes color with height (low → blue, high → red).
- Drag & Wind Effects: Adjust air resistance and horizontal wind to see their impact.
- Custom Parameters:
- Initial velocity
- Launch angle
- Drag coefficient
- Time step (
dt) - Wind speed (positive = tailwind, negative = headwind)
- Data Table: Displays time, X, and Y coordinates for each step.
- Export Options:
- Save trajectory data as CSV
- Download the plot as PNG
The simulation models projectile motion under gravity, air drag, and optional wind effects using small time-step numerical integration: vx_next = vx - drag * vx * dt + wind vy_next = vy - (g + drag * vy) * dt x_next = x + vx * dt y_next = y + vy * dt
