What is takeoff velocity of rocket?
Exactly the same way it takes off from the earth. Gravity on the moon is so relativistically low that the propulsion required to reach an escape velocity is very very low compared to the earth.
Explain how a rocket works?
A bottle rocket is like a firecracker on a stick. The bottle rocket is placed at an angle in a soda bottle that is firmly on the ground. Then the bottle rocket's fuse is lit. When the fuse burns down there is an abrupt explosion in the bottom of the rocket that forces it to fly up. When it burns all the way up the bottle rocket, gun powder in the tip of the rocket explodes in the air.
How can rockets escape from gravity?
Escape velocity is defined to be the minimum velocity an object must have in order to escape the gravitational field of the earth, that is, escape the earth without ever falling back. From the surface of the Earth, escape velocity (ignoring air friction) is about 7 miles per second, (11.2 km/sec) or about 25,000 miles per hour. Given that initial speed, an object needs no additional force applied to completely escape Earth's gravity. More can be seen about this in the related link below.
To escape from a planet's an object muct reach a speed called the?
That would be its escape velocity.
How does the sound from the loudspeakers reach the audience?
Because of the gravity of the earth
Why must a spacecraft reach escape velocity to be able to go to space?
A rocket needs to travel at 7 miles-per-second or about 25,000-miles-per-hour to leave the pull of earth's gravitational force, and reach outer space. This speed is known as escape velocity.
What may happen to a rocket which rises from the earth never attains escape velocity?
A rocket that doesn't reach "escape velocity" will be overcome by gravity and will be pulled back down to Earth. Also, rockets which go into orbit have not reached escape velocity. Escape velocity is what is needed to completely leave earth's gravity well.
How is the force of earths gravity overcome when an object is launched into space?
When on Earth, you can escape if you move away from the Earth at the "escape" speed. Gravity will slow you down and you will reach zero speed at an infinite distance.
What kind of force is needed to launch rocket ships?
to break off from earths gravity they need to reach speed of 11.2 kilometers per second
With the right ramp and a motorcycle could you reach escape velocity on the Moon?
Your motorcycle would have to reach 5300 MPH to escape the moon's gravity. It's doubtful that a real world motorcycle, even rocket propelled could do this with a human sitting on it.
How do you beat gravity on Earth?
To overcome gravity, you must reach "Escape Velocity" to overcome gravity and escape a planet's orbit.
How long does it take to escape gravity in a rocket?
It isn't clear what exactly you mean with "escape gravity". The effects of Earth's gravity (for example) extend all the way to infinity, while getting weaker and weaker at a greater distance. So in a way, an object moving away from Earth never "escapes gravity". If an object moves fast enough - about 11.2 km/second near Earth's surface - it is said to have reached "escape velocity", in this case, it is fast enough never to come back. A rocket will reach escape velocity in a few minutes.
What is the main force a rocket must overcome to reach orbit?
gravity
To escape from a planets gravity an object must reach a speed called the?
Escape Velocity
Why can't you fly a model rocket into a cloud?
Gravity will pull it down before the rocket can reach the height where clouds form.
To reach outer space rockets must escape what force?
gravity
What is takeoff velocity of rocket?
Exactly the same way it takes off from the earth. Gravity on the moon is so relativistically low that the propulsion required to reach an escape velocity is very very low compared to the earth.
