📚 Physics Concepts
Why do we fall?
Gravity pulls everything down at 9.8 m/s²
Force = Mass × 9.8
What slows us down?
Air resistance (drag) increases with speed
Drag ∝ Speed²
Terminal Velocity:
When drag equals gravity, speed becomes constant (~55 m/s or 200 km/h!)

📖 How to Use This Simulator

🎮 Controls:

  • Click "START JUMP" to begin
  • Click "OPEN PARACHUTE" when falling (deploy between 500-1000m)
  • Press SPACE key to deploy parachute quickly
  • Click "RESET" to start over

🔬 What You'll Learn:

  • Gravity: Constant force pulling you down (9.8 m/s²)
  • Acceleration: Speed increases as you fall
  • Air Resistance: Wind pushes back harder as you go faster
  • Terminal Velocity: Maximum speed when forces balance
  • Parachute Effect: Increases drag, slows descent safely

🎯 Try These Experiments:

  • Change weight - heavier objects reach higher terminal velocity
  • Change height - more time to accelerate from higher altitude
  • Deploy parachute at different heights - see the effect!
  • Watch how speed increases then levels off (terminal velocity)

⚠️ Safety Tips:

  • Deploy parachute above 500m for safe landing
  • Below 500m = DANGER ZONE!
  • Watch your speed - it should slow down after parachute opens
  • Safe landing speed is below 8 m/s
