Thrust Equation

The thrust equation describes how the force generated by a rocket or jet engine depends on how much air or exhaust it pushes out and how fast it moves. Essentially, it states that thrust equals the mass flow rate (how much air/exhaust is expelled per second) multiplied by the velocity of that expelled mass, minus the velocity of the incoming air. This means that faster exhaust or more mass being expelled increases the thrust, allowing the vehicle to accelerate and move forward. In simple terms, engines work by pushing mass backward quickly to produce a forward push or thrust.
