What does a rocket need to take off?
A rocket needs a powerful thrust to overcome Earth's gravity and lift off. This thrust is typically provided by rocket engines that burn fuel to create a force that propels the rocket upward. Additionally, the rocket needs a stable structure to withstand the forces of liftoff and the harsh conditions of space.
How much thrust does a rocket need to get to outer space?
A rocket needs enough thrust to overcome Earth's gravitational pull and achieve the required velocity to reach outer space, typically around 25,000 mph (40,000 km/h). The exact thrust needed depends on various factors such as the rocket's size, weight, and the altitude it needs to reach.
How is gravity and thrust both involved when launching a rocket?
Gravity plays the major role in the launch.. a rocket has to cross the escape velocity so as to get out of the atmosphere. Escape Velocity is the speed at which any space shuttel or rocket or anything has to achieve if it wants to escape the earth's gravitational field. Gravity attracts the rocket and all the things coming from the space and going in to the space from the earth towards itself.. that is the reason that whenever you jump, you come back to earth!!!
What kind of force is needed to launch rocket ships?
Rocket ships are launched by a combination of forces, including the thrust generated by the rocket engines and the force needed to overcome gravity. The thrust from the rocket engines propels the rocket forward, while the force needed to overcome gravity allows the rocket to lift off the ground and enter into space.
What does a rocket need to go into orbit?
A rocket needs a powerful engine to provide enough thrust to overcome Earth's gravity and reach orbital velocity, typically around 28,000 kilometers per hour. It also needs a guidance system to ensure accurate trajectory and a payload, such as a satellite or spacecraft, that is destined for orbit. Finally, a rocket needs a heat shield to protect it during atmospheric re-entry if it is intended to return to Earth.

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 force is need for a rocket to enter the earth?
gravity
What thrust does a 190 gram model rocket need in order to have a vertical acceleration of 11.0 meters per second squared on earth?
F = m Am = 0.19A = 11F = (0.19) x (11) = 2.09 newtons upwardBut there is another force on the rocket = (m g) = (0.19) x (9.8) = 1.862 newtons downward.The engine also has to cancel this force.Total engine thrust required = (2.09 + 1.862) = 3.952 newtons.

How does a rocket change its speed in space with no air?
Some people (who have not studied physics) believe that rockets work because the rocket exhaust pushes against the air, and therefore in the vacuum of space where there is no air, rockets won't work - but that is not the case. Rocket exhaust doesn't need to have air to push against. The expanding gases in the rocket's exhaust nozzle push against the rocket. The gas has its own mass and its own inertia, and the change in momentum of the exhaust gas causes an opposite change in momentum of the rocket. This can be difficult to grasp because we think of gas as being virtually weightless, but a large rocket can emit literally tons of exhaust. The fact that it is in the form of a gas doesn't change the result; mass is mass, whether solid, liquid, or gas.This is WRONG, rocket DOES work in space.From NASA"A rocket is a type of engine that pushes itself forward or upward by producing thrust. Unlike a jet engine, which draws in outside air, a rocket engine uses only the substances carried within it. As a result, a rocket can operate in outer space, where there is almost no air."How it accelerate"Rocket engines generate thrust by putting a gas under pressure. The pressure forces the gas out the end of the rocket. The gas escaping the rocket is called exhaust. As it escapes, the exhaust produces thrust according to the laws of motion developed by the English scientist Isaac Newton. Newton's third law of motion states that for every action, there is an equal and opposite reaction. Thus, as the rocket pushes the exhaust backward, the exhaust pushes the rocket forward.The amount of thrust produced by a rocket depends on the momentum of the exhaust -- that is, its total amount of motion. The exhaust's momentum equals its mass (amount of matter) multiplied by the speed at which it exits the rocket. The more momentum the exhaust has, the more thrust the rocket produces. Engineers can therefore increase a rocket's thrust by increasing the mass of exhaust it produces. Alternately, they can increase the thrust by increasing the speed at which the exhaust leaves the rocket."http://www.nasa.gov/worldbook/index.html
How does a spacecraft launch from earth?
the fuel needed is huge but you need to take in the power and the amount of thrust
Why does a shuttle need thrust?
To lift off the earth against the force of gravity. To go up.
How does a rocket turn in if there is no air resistance in space . What does it push against. What resists the thrust?
There is no need for air resistance, nor does the thrust need to push against anything. The energy of firing a rocket pushes the exhaust gasses out and, in accordance with Newton's Third Law, the gasses push back on the rocket with the same amount of force, but in the opposite direction. By firing gas jets or rockets that are not aligned with the center of mass, that force exerts torque, which allows a rocket to turn.
