What is Rocket speed per sec to escape from earth gravity?
the rocket speed required to escape out of the earth's gravity is known as escape velocity which is numerically equal to 11.2 km per sec.
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

Rocket A travels with speed 0.800c relative to the earth Rocket B passes rocket A with speed 0.500c relative to rocket A Determine the speed of rocket B relative to the earth Assume that the earth?
0.929c formula is: vbe =( vae +vba )/(1+( vae *vba )/c2 )
What can a force do to a rocket that is moving at steay speed?
A force can change the direction of the rocket's motion but not its speed if the force is applied perpendicular to the rocket's velocity. If the force is applied in the same direction as the rocket's motion, it can accelerate or decelerate the rocket.
Can the weight on a rocket affect the speed?
Yes. A heavier rocket will need more energy to achieve a certain speed.
The speed of a rocket in a given direction is?
determined by the rocket's thrust and the mass of the rocket. The speed of the rocket can also be influenced by external factors such as gravity and air resistance. Ultimately, the goal is to achieve enough speed to overcome these forces and reach the desired velocity.
What is the speed of a rocket that travels 25000 miles?
The problem/question can not be solved, because to calculate the speed of the rocket you need the distance done by the rocket and the time interval.
How is hydrogen used in rocket fuel?
it is used to rise the speed of the rocket.
Why is George stephenson's Rocket called the Rocket?
because of it's speed.
What is the speed of a rocket that travels 9000 meters in 30 seconds?
what is the speed of a rocket that travels 9000 meters in 12.12 seconds
What speed rocket starts?
A rocket's speed at launch is typically zero, as it starts from a stationary position on the ground. The rocket gradually accelerates as it is propelled by its engines, reaching higher speeds as it ascends into space.
Speed of fastest rocket?
400000
What is use of nose cone in rocket?
It streamlines the rocket and allows more speed.
Does the size of a rocket affect its speed?
The size of a rocket does not directly affect its speed. The speed of a rocket is determined by factors such as its engine power, fuel efficiency, and aerodynamics. However, a larger rocket may have more room for larger engines or additional fuel, allowing it to potentially achieve higher speeds.
