For Every Action (Force), There Is An Equal And Opposite Reaction (Force).
A rocket in space operates off the expelled mass, from the conservation of momentum, dmv/dt = mdV/dt + Vdm/dt =0, The rocket is acceleration is mdV/dt = -Vdm/dt. The exhaust is Vdm/dt which is the force pushing the rocket forward as the exhaust goes out.
The rocket's propellant shoots out of one of its ends. Newton said that every action (like rocket propellant shooting out) is accompanied by an equal (same force) but opposite re-action. So, if the propellant shoots out with a force of, say, 1,000 pounds, then the rocket is pushed in the opposite direction (forward, we hope) by 1,000 pounds. It works! Try standing on one tiptoe while holding a weight of 5 or 10 pounds out to your side. Move the weight quickly sideways across your body and you will find your body moving (twisting because of that toe on the floor) in the opposite direction.
At the top of the rocket's trajectory it is motionless for a brief time and the only force acting on it is that of gravity; the rocket motor has long since spent its energy.

It is not the action but the reaction force that makes a rocket lift up. The action force is the force released when the rocket fuel burns. This action force acts on the surface/ground and according to Newton's Third Law [For each and every action, there is an equal and opposite reaction], a reaction force acts towards the rocket hence giving it a lift.
Rockets have an exhaust of hot gas, moving rapidly away from the rocket, which is the action, and the reaction is that the rocket is propelled forward.
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.
Pressure is the force that launches the bottle rocket once it has launched this pressure starts to dissipate until no other force is driving the rocket to overcome gravity, therefore gravity is now the only force acting on the object and as such the bottle falls back to earth

If you are in Science Olympiad, a bottle rocket is a modified 2 liter bottle designed to stay up in the air longer than its competitors. Another type of bottle rocket is a type of firework you place in a bottle to make it launch.
Bottle Rocket was created in 1994.
i think is friction but dont believe
