Endogenous factors are those that are directly related to the system being studied, and can be controlled or manipulated by the experimenters. In this case, the size of the rocket engine is an endogenous factor that the experimenters can control and manipulate to test the rocket. The other factors listed (wind speed, elevation/air pressure, precipitation, and gravitational pull) are exogenous factors that cannot be controlled by the experimenters and may affect the rocket's flight, but are not directly related to the system being studied.
