Momentum is mass times velocity. Without knowing the speed of the rocket, momentum cannot be calculated.
Thy operate on the same principle. The water going backwards has momentum that is balanced by the rocket going forward.
When it comes to water bottles, there is downward momentum, which creates an upward momentum. The reason for this is the conservation of momentum. That's why the water bottle is driven upward. The downward momentum is created by the water mass times water's velocity.
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
The biggest disadvantage of a horizontal waterwheel is that the weight of the turning wheel works the most against the current in this situation. In vertical waterwheels, the momentum of the descending parts isÊadded to by its own weight.
a rocket powered by water
it will become an air powered rocket

The angle of the rocket. The amount of water in the rocket.
Chemical rockets combine a fuel chemical and an oxidizer chemical to produce combustion products (a new, combined chemical with an ever-so-slightly lower mass than the components, and lots of energy). In the space shuttle main engine (SSME) the fuel was liquid hydrogen (other common liquid fuels are alcohol and kerosene) and the oxidizer was liquid oxygen. The rocket engine is a bell with an open end, or nozzle. When the hydrogen and oxygen are combined in the bell, they burn to produce water vapor and energy. The released energy forces the mass of the water vapor out the open end of the engine in one direction and, by conservation of momentum (Newton's third law), the mass of the rocket is propelled in the opposite direction. So, rather than a specific additive, everything that is burned in the engine provides mass that contributes to the momentum that propels the rocket.
the rocket is pushing water downwards which means that the water pushes the rocket upwards very hard that it can overcome gravity and fly.
If you have leaks in a water bottle rocket, the pressure will quickly escape along with the water and the rocket won't be able to reach as high an altitude as a rocket without leaks.
There are two forces acting on a water rocket. The thrust which the force that is given to the water rocket to make it move, and the other one is the gravity.
