👉 Prethrust is a term that refers to the thrust generated by a rocket or other aircraft engine when it is in flight. It is typically represented as "P" (for pressure) and represents the amount of force generated by the engine during lift off. In a rocket, prethrust can be used to generate thrust, which helps to propel the rocket forward and lift up the fuel. The amount of prethrust needed for a given thrust is determined by the rocket's design and the characteristics
