🎮 3D Projectile Motion Simulator

A comprehensive physics simulation application with a dark, minimalistic aesthetic.

✨ Key Features

🌑 Dark Aesthetic Theme

  • Primary Colors: Black, White, Gray
  • Accent Colors: Blue (trajectories), Yellow (highlights)
  • Design: Minimalistic and clean
  • Background: Almost black (RGB: 13, 13, 13)
  • Grid: Dark gray for subtle ground reference
  • No Clutter: Coordinate grid lines don't overwhelm the view

🎯 3D Objects with Realistic Physics

8 Different Object Types:

Object Mass (kg) Size (m) Shape Use Case
Football 0.43 0.11 Sphere Sports simulation
Basketball 0.62 0.12 Sphere Heavier ball physics
Baseball 0.145 0.037 Sphere Fast, light projectile
Small Cube 1.0 0.1 Cube Standard weight test
Large Cube 5.0 0.2 Cube Heavy object physics
Spear 0.8 0.3 Cylinder Long projectile
Arrow 0.02 0.15 Cylinder Light, fast projectile
Bullet 0.008 0.02 Sphere Extreme speed test

🎯 Usage Examples

Example 1: Long Distance Shot

Object: Football
H-Angle: 0°
V-Angle: 45°
Force: 50N
Result: ~25m horizontal distance

Example 2: Vertical Launch

Object: Basketball
H-Angle: 0° (doesn't matter)
V-Angle: 90°
Force: 30N
Result: Goes up ~15m and falls back down

Example 3: Mass Comparison

First: Bullet @ 10N force
   → Travels very far (light mass)

Second: Large Cube @ 10N force
   → Barely moves (heavy mass)

Example 4: Angle Optimization

Test different V-Angles:
30°: Good distance
45°: Maximum distance
60°: Less distance
75°: Very little distance
