Pressure builds up, and when it is released it forces the rocket up.
Rockets fly by producing thrust.Thrust is the force that moves the rocket foroward.Thrust occurs because forces always come in pairs.
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.
by water being placed into the bottle and then, when you launch your rocket, the rocket will spin (if it has at least 2 fins) and the water will spurt out and make the rocket go higher in the air. (Tip:the more it spins,the higher it will fly)
vinegar
alkaselser and water
look mass times acceleration equals potential gravity this causes rockets to launch
That means there is no air. There is "vacuum". A rocket can fly in space without air. A rocket or rocket vehicle is a missile, aircraft or other vehicle which obtains thrust by the reaction of the rocket to the ejection of fast moving fluid from a rocket engine. Chemical rockets work by the action of hot gas produced by the combustion of the propellant against the inside of combustion chambers and expansion nozzles. This generates forces that accelerate the gas to extremely high speed and exerts a large thrust on the rocket.
Thrust and Lift. Gravity and drag make planes more difficult to fly.
well it will need to make the forces unequal to take off, but yes it can fly with them all equal.
Get a huge bottle of soft drink (Cokes good), place mentos inside and shake bottle. leave the lid on loosely. Place a rocket on top, then, watch it fly!!
you need to put power-ups in the rocket to make it fly
