Enough to support their own weight, plus a little more for motion. It is possible, in theory, to imagine a rocket moving away from the Earth at a slow walking pace. In real life you don't do that, you get away from Earth's pull as quickly as you can manage to do so.

What speed do firework rockets travel at?
speed of rocket fire work
What speed does an object have to go to break free of the atmosphere?
If you want it to get away from Earth's gravitational field, the object would need a speed of 11.2 km/sec - obviously not considering energy lost by friction with the atmosphere.If you want it to get away from Earth's gravitational field, the object would need a speed of 11.2 km/sec - obviously not considering energy lost by friction with the atmosphere.If you want it to get away from Earth's gravitational field, the object would need a speed of 11.2 km/sec - obviously not considering energy lost by friction with the atmosphere.If you want it to get away from Earth's gravitational field, the object would need a speed of 11.2 km/sec - obviously not considering energy lost by friction with the atmosphere.
Does the earths rotation speed up from the moon?
No. Just the opposite. The earth's rotation is slowing down because of the gravitational force between the earth and the moon. The day is getting longer by something like a millisecond (0.001 second) every hundred years.
Why would a rocket have to travel at a faster speed to escape Jupiter's gravitational pull?
Jupiter's gravitational pull is much stronger than that of Earth.
What is the earth greatest speed of earths rotation?
The speed of rotation is greatest at the equator; 1038 miles per hour.
Why does the United States launch rockets from Florida?
The rockets are launched easterly and get the benefit of of the speed of the earths rotation and there is the entire Atlantic Ocean for safety.
Ignoring air resistance what is the minimum initial speed a projectile must have at the Earths surface if the projectile is to escape the Earths gravitational pull?
8km/s
What is the speed necessary to escape the earths gravity?
The speed at which a rocket must travel to escape the gravitational pull of the earth is 25,000 miles per hour.
What speed do firework rockets travel at?
speed of rocket fire work
Speed of Apollo rockets?
1400m/sec
What causes the moon to speed up or slow down slightly in its orbit?
the moon speeds up and slows down because of atmospheric drag and tidal dynamics
How fast does Saturn v go?
over 24,000 miles per hour, on the final burn, which is 7 miles per second, which speed is needed to escape earths gravitational pull.
Why gravitational force increases when you fly with supersonic speed?
Gravitational force depends only on an object's mass and its distance from the center of the earth. Its speed has no effect on the gravitational force.
What is meant by the 'escape velocity' of a rocket leaving the earth?
There is a speed, about seven miles a second, that if reached, will allow an object to overcome the earth's gravitational pull and continue into space. Rockets don't actually need to do this speed, since their objective is usually to establish an orbit around the earth.
How does the hubble telescope travel?
Well at first the rockets prepel it up into space giving it i guess 50 to 100 miles ph. But when passing planets it gets grabbed by the planets gravitational pull and when it comes out it will get a boost of speed.
How high can model rockets go?
Once it has managed to escape the Earths gravitational pull and then the suns gravitational pull, a space craft will have enough speed to carry on indefinitely, so long as it does not collide with anything. If it has enough fuel and thrust to get up to this escape speed, then it wont stop, since there will be no forces to slow it down in space, even once the engines have stopped.
Does speed affect gravitational potential energy of an object?
Does speed 'effect' the gravitational potential energy of an object? No, but gravitational potential energy can be converted into kinetic energy - so the gravitational potential energy can effect the speed. Ep = mgh Energy Potential = mass * 9.81 (gravity) * height Speed / Velocity is absent from that equation.
