The Physics of Apogee
I genuinely believe that model rocketry is one of the best ways to learn physics. When you ignite an engine, it produces a specific amount of force (thrust) for a short period. This "Total Impulse" accelerates the rocket to its maximum velocity. After the motor burns out, the rocket "coasts" upward, fighting both gravity and air resistance (drag) until it reaches its highest point, called **Apogee**.
The Drag Factor: Air resistance is the biggest variable in rocketry. A smooth, painted rocket with thin fins will reach a significantly higher altitude than a cardboard rocket with thick, square fins. Our calculator uses a standard drag model to provide a realistic estimate.
Launching Safety:
- Wind: Never launch in high winds. The wind can catch your rocket's fins and tilt it horizontally, which is extremely dangerous.
- Clearance: Ensure you have a large, open field with no trees, power lines, or buildings nearby.
- Recovery: Most rockets use a parachute or streamer. Ensure your recovery system is packed correctly to prevent "lawn-darting."
