What else can I help you with?
What is the speed a rocket needs to go past Earth's gravitational force?
Escape velocity from Earth is approximately 11.2 km/s, which is the speed a rocket needs to surpass Earth's gravitational force and leave its orbit.
Why does the rocket have to go sideways?
The rocket needs to go sideways to reach orbit. By moving sideways fast enough, the rocket can overcome the force of gravity pulling it back towards Earth. This sideways velocity allows the rocket to enter a stable orbit around Earth.
What speed does a rocket have to reach to get into space?
(Escape velocity) at least 7 miles ber second. Close-Orbital velocity is about 5 miles per second.
Why does a rocket need a large thrust on take off from the earth?
A rocket needs a large thrust on takeoff from Earth to overcome the force of gravity pulling it down. The large thrust is necessary to generate enough speed to reach escape velocity and break free from Earth's gravitational pull. Once the rocket is in space, it needs less thrust to maintain its course.
What you do to send a rocket into space?
To send a rocket into space, you need to first assemble the rocket, fuel it, and then launch it into the atmosphere. The rocket needs to achieve enough velocity and altitude to escape Earth's gravitational pull and enter space. This involves careful planning, engineering, and coordination of various systems to ensure a successful launch.
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.
How fast does the shuttle rocket have to accelerate to get into space?
The shuttle rocket needs to accelerate to about 17,500 miles per hour (28,000 kilometers per hour) to reach low Earth orbit. This acceleration allows the rocket to overcome Earth's gravity and achieve the necessary speed to enter space. The acceleration rate can vary depending on the rocket design and mission requirements.
How can a rocket change its velocity?
It could - but that's not the idea (except from start to whatever velocity you select). Since the rocket must reach either escape or orbital velocity (25000 mph or 18000 mph), if you could start off with that speed, the sudden jerk would tear it apart.
Does a rocket always need the escape of 11.2 to escape the earth?
That's the initial speed the rocket would need to escape Earth, assuming it starts close to Earth, and no additional impulse is provided later. With a gradual impulse - for example an ion impulse - i.e., providing impulse over time, it isn't necessary to start with this speed. However, the rocket still needs the same total amount of energy to escape from Earth.
What is the difference between rocket flight and airplane flight?
A plane needs air, a rocket doesn't.
What is the speed of the rocket to reach Jupiter?
The speed of a rocket required to reach Jupiter varies depending on the trajectory chosen and the specific mission parameters. However, it typically needs to reach a velocity of about 130,000 miles per hour (209,214 kilometers per hour) to complete the journey in a reasonable amount of time.
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.
