thrust
thrust
Rockets exert force at the upper part of the combustion chamber. This pushes the rocket forward.
Thermal expansion of the combusting gases in the rocket nozzles (bottom of the rocket) pushes them against the outside air, and the equal-and-opposite reaction is to push the rocket upward.
Thrust
A rocket engine is a reaction engine as the fuel is burnt the thrust created pushes the rocket forward. Newton's 1st law in action; for every reaction there is a equal and opposite reaction.
The force of the combustion pushes on the interior of the rocket. The combustion releases through the rear exhaust, causing the rocket to move forward.
Newton's third law is that every action has a reaction that is equal in magnitude but opposite in direction. So, for a rocket, the rocket releases force in the backward direction (in the opposite direction it is moving) which enables it to go forward. You can try this at home using a balloon and a string.
Well, according to Newton's third law of motion, for every action there is an equal and opposite reaction, so when the gas pushes against the ground, the ground "pushes" back, forcing the rocket upwards.
Rocket emits particles backward with great force. This means that there is also a force in the other direction, which pushes the rocket forward. Also apparent from conservation of momentum.
The first "rocket" successfully launched into space was actually a V-2 missile. The first rocket-ship that was successfully launched into space used rocket engines. A rocket engine pushes the rocket forward by expelling its exhaust in the opposite direction at a high speed.
Thrust is the force that pushes something (typically a rocket) forward. The term force is more general; there are many kinds of force.
In the rocket engine large amount of fuel are burnt. The burning fuel expands and is forces itself out the bottom of the rocket. As it pushes down, it pushes the rocket up. If the force pushing the rocket up exceeds its weight, the rocket will take off.
