Expert Answer
Rocket propulsion
Figure : 5
In the figure 1, it is shown how the rocket moves in the space by following the Newton's third law. Actually, when rocket moves in the space it pushes the gas outside from it, i.e., rocket applies force on the gases in the backward direction. As a reaction, the gases put equal amount of force on the rocket in the opposite direction and the rocket moves in the forward direction.
Figure : 5
Pressure pushing the exhaust gases DOWN, out of the rocket is the reaction force.
When a rocket rises,, Gravity is the action force.
