What is the energy source a rocket?
momentum
How do rockets navigate?
The chemicals in the rocket take in the oxygen from the air behind the rocket and then explode in all directions. As there is less oxygen behind the rocket the thrust goes in that direction more and forces the rocket forwards.
How does a rocket use inertia?
As a rocket enters space, there is no opposing force to slow it down, so as it continues, it loses no momentum. THere is no outside force to act on it to slow so it can save fuel.
How did you explain conservation of momentum when a rocket ship takes off?
Momentum P of a body with mass m and velocity v is given by:P = m∙vNewton's first law of motion establishes conservation of momentum on abody as long as there is no net force applied on it.Let's assume our Rocket Ship is about to be launched from the surface ofa planet with no gravity force, so we can leave out the influence of thisforce from the discussion.At time t ≤ 0 from launch, the Rocket Ship's velocity v is zero, and soits momentum P is also zero.When the Rocket Ship starts his motion upwards, the initial system (theRocket Ship), is now conformed by two subsystems: The Rocket Ship goingup and the exhaust gases being sent down.To give a simple view of what happens, lets assume that the massof the exhaust gases is expelled at a constant velocity vg through the wholeprocess till the Rocket Ship's engine stops. Then the final condition ofmomentum would be:P = mR∙vR + mg∙vg = 0where mR and mg are the final Rocket Ship's mass and the total mass ofexhaust gases expelled respectively, and vR the Rocket Ship's final velocity.You have to realize that the vectors of velocity VR and Vg will have oppositesigns.If we now would want to include the planets gravity force, this willbe affecting the momentum of the Rocket Ship by producing an accelerationin the opposite direction of its velocity. If we now think of the originalsituation of Rocket Ship and planet at rest, when the Rocket Ship ispushing away from the planet the gravitational attraction between theRocket Ship and planet works both ways. And so the lose of momentumby the Rocket Ship because of the gravitational force is compensated bythe planets lose of momentum in the opposite direction !.
What is the force that accelerates a rocket called?
The combustion of rocket fuel ejects a mass of material at high velocity. In accordance with Newton's third law, the momentum of the ejecta generates an equal and opposite reaction - which propels the rocket forward.
How does launching your rocket relate to this law of motion?
If a rocket is at rest (zero momentum) in outer space, where there is no gravity, then as long as there are no Outside forces on it its momentum must always be zero (consevation of momentum). This must be true even if an internal explosion brakes it into pieces. The pieces must fly off in such a way that their net vector momentum is zero. Turning on the engine is like an internal explosion. The hot gasses, which have mass, are ejected out the back at high velocity so the gas has momentum. In order to keep the total momentum zero the rocket must move forward so its momentum just equals the backward momentum of the gasses and the net momentum of both is zero. The same is almost true when taking off from earth. Because of the Earth's gravity(outside force) the upward momentum of the rocket won't quite equal the downward momentum of the gasses but its almost the same.
What is the Momentum of a water rocket with the weight od 1185.5ml?
Momentum is mass times velocity. Without knowing the speed of the rocket, momentum cannot be calculated.
What is the energy source a rocket?
momentum
Is there momentum in a moving rocket?
yes
Rocket works on the principle of conservation of?
linear momentum. A rocket works by expelling gases from one end at a very high velocity. The escaping gases have a very high speed and this with their mass translates to a very large momentum. Due to the principle of conservation of momentum the body of the rocket is pushed forward. If both the momentum of the gases as well as that of the rocket are added the sum is zero.
How does a rocket travel?
By expelling hot gasses extremely fast from the rocket nozzle. Due to the conservation of momentum, expelling mass at high velocity causes the rocket to gain momentum and therefore velocity.
How is it possible for a rocket to propel itself through space?
This is possible via the conservation of momentum. A rocket ejects matter from its back and this matter carries momentum. To conserve momentum the rocket must gain an equal amount of momentum in the opposite direction. Since momentum is related to velocity this causes the rocket to move. This is basically an application of Newton's third law. You might have been confused with the situation in air. For example an airplane moves through air by pushing air past it (using its propeller). This accelerates the air, and thus increases its momentum. The airplane must therefore gain momentum in the opposite direction, and accelerates itself as well. The only difference between the airplane and the rocket is that the rocket carries the stuff it accelerates (and ejects) while the airplane can use the air that is already present all around it. Note that while this is the basic explanation, the situation with the rocket is made somewhat more complicated by the fact that as the rocket loses fuel it also loses momentum because momentum is velocity times mass and the lost fuel lowers the mass of the rocket. You might want to look up Tsiolkovsky's rocket equation if you want more information.

Does the thrust of a rocket need to be created by an explosion?
no, the thrust of a rocket relies on the trajectory of the rockets tilt and overall slanted angle. The rocket is sent via a useful queef, that blasts the rocket from the platform
What kind of force is it when rockets escape from gravity?
If the rocket has a certain speed, it will escape from gravity due to its own momentum. To speed the rocket up, currently chemical combustion is used. The burning gas goes out in one direction, thus pushing the rocket in the opposite direction.If the rocket has a certain speed, it will escape from gravity due to its own momentum.

How do you make a bottle rocket with explosion at the end?
put a cherry bomb in it and time it.
