^Rocket propulsion

Multistage rockets used in satellite launching work on

NTL’s & conservation of linear momentum.

The burnt gases are allowed to escape through a small nozzle with a very high velocity such that the rocket acquires an equal momentum in the opposite direction to conserve momentum.

Followig relations (Instantaneous) for used in the vertical firing of a rocket.

For a rocket moving horizontally put, g = 0.
