On what principal the rocket propulsion is based? Find out thrust acting on the rocket amd the burnt out speed of the rocket
Answers
Rockets move and accelerate as a result of Newton’s 3rd Law, which states “for every action, there is an equal and opposite reaction.” Mass (in the form of exhaust) being ejected out the back end of the rocket pushes it forward. This essentially creates an equal and opposite reaction in the form of a “push.”
This principle is extremely easy to observe and test here on the Earth. Say you’re standing on a skateboard and you throw a bowling ball forward. This initial throw causes you to accelerate to some degree in the opposite direction of the throw, but since your weight is (most likely) heavier than that of the bowling ball, you won’t move very far. However, you still move somewhat. This principle offers many challenges in the form of rocketry and even explains why a significantly larger amount of fuel is needed per pound of payload.
Rocket is based on Newton's third law of motion : every action has an equal and opposite reaction (Fab = -Fba).
Thrust is the upward force on a rocket perpendicular to the ground.
Thrust of a rocket can even reach 3 lakh pascals.
Burnout speed is the maximum velocity achieved by a rocket at the exhaustion of it's fuel.
Burnout speed of a rocket can even reach Mach 20.
