Editing Model rocket (section)

=== Instrumentation and experimentation ===

Model rockets with [[electronic altimeter]]s can report and or record electronic data such as maximum speed, acceleration, and altitude. Two methods of determining these quantities are to a) have an accelerometer and a timer and work backwards from the acceleration to the speed and then to the height and b) to have a barometer on board with a timer and to get the height (from the difference of the pressure on the ground to the pressure in the air) and to work forwards with the time of the measurements to the speed and acceleration.

Rocket modelers often experiment with rocket sizes, shapes, payloads, [[multistage rocket]]s, and recovery methods. Some rocketeers build scale models of larger rockets, space launchers, or missiles.
