Propulsion is the force that moves an object forward. It is the result of applying force to the object in the opposite direction it needs to move. For example, in a rocket, propulsion is generated by expelling propellant gases backwards, causing the rocket to move forward.
A rocket moves forward by expelling high-speed gases out of its engines, in accordance with Newton's third law of motion. As the gases are ejected downward, an equal and opposite reaction force propels the rocket forward. This principle is known as action and reaction.
Rockets are propelled forward by thrust generated by the combustion of rocket fuel and controlling the direction of the exhaust.
One of Newton's Laws of Motion- for every action, there is an equal but opposite reaction. Rocket motors eject gasses from burning rocket fuel with great force. Their action (going to the rear) causes the rocket to react- being pushed forward.
Thrust
A balloon rocket moves forward due to the principle of action and reaction as outlined in Newton's Third Law of Motion. When the air is forced out of the balloon in one direction, the balloon is propelled forward in the opposite direction.
Rockets exert force at the upper part of the combustion chamber. This pushes the rocket forward.

The third law of motion, known as Newton's third law, is used to explain rocket propulsion. This law states that for every action, there is an equal and opposite reaction. In the case of a rocket, hot gases are expelled backward, causing the rocket to move forward in the opposite direction.
The rocket is pushed forwards by the reaction to the force ejecting gas in the opposite direction to the direction of travel of the rocket. Rocket flight is an example of Newton's 3rd law of motion, which states that every action (force) has an equal and opposite reaction. In this case, the action is the ejection of rocket gas and the reaction is the forward force on the rocket.
Thrust ... [ :
Rocket reaction force, also known as thrust, is the force exerted by a rocket engine to propel the rocket forward. This force is generated by the combustion of fuel in the rocket engine and is directed opposite to the direction in which the rocket travels. The magnitude of the thrust determines the acceleration of the rocket.
