An object leaving the surface of the Earth would need to move at about 11.2 km
(7 miles) per second ... about 34 times the speed of sound!
If it did that, (and if there were no air dragging on it), then it could shut off the
rocket engines, and gravity could never pull it back to earth.
If the object is already some distance above Earth's surface, then the required
speed is less.
What else can I help you with?
Can a slow object travel as far as a fast object?
Yes, a slow object can travel as far as a fast object given enough time. The distance traveled depends on the speed of the object and the duration of its travel.
What most determines how fast an object will fall on earth?
The acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth, is the primary factor that determines how fast an object will fall. Objects will fall faster if they have a higher acceleration due to gravity and slower if they have a lower acceleration due to gravity. Other factors like air resistance and the density of the object can also have a small effect on the speed of fall.
Does the air in a ball affect how fast it falls?
No, the air inside a ball does not affect how fast it falls. The rate at which an object falls is determined by gravity and the air resistance it encounters, not the properties of the air contained within the object.
What is useful to calculate an object's average speed when it does not travel?
When an object is stationary and does not travel, calculating its average speed is not useful since there is no displacement or time taken to travel. Average speed is typically used to measure how fast an object moves over a period of time, which does not apply to a stationary object.
Could a Gyroscope spinning fast enough counter act gravity?
No, a gyroscope spinning fast enough cannot counteract gravity. Gravity will always exert a force on an object regardless of its speed. The gyroscope may provide stability or resistance to external forces, but it cannot cancel out the effect of gravity.
How fast does something need to be to escape the gravity of a black hole?
In order to escape the gravity of a black hole, an object would have to travel faster than the speed of light - something that is impossible.
Can a slow object travel as far as a fast object?
Yes, a slow object can travel as far as a fast object given enough time. The distance traveled depends on the speed of the object and the duration of its travel.
How do clouds defy gravity?
To say clouds defy gravity would be misleading, as they do not defy gravity. However rising air currents keep the clouds in the air. The air currents are stronger than the rate at which gravity makes the rain fall (which is not that fast). Clouds are so light, that even the smallest upward air current can make a clouds stay up. Rain falling is basically when the mass of the drops exceed the air currents.
Why does a space shuttle have to travel so fast?
Space shuttles must travel at 11km/s so that they can escape the force of gravity. the force of gravity is approximately 9.81. If you don't travel at a greater speed than the force of gravity, the rocket will not launch.
When does the mass and or size of an object affect the time of its free fall?
if an object is lightr it will fall slower because gravity wont take it down as fast if it is heavier it will make the gravity pull it down faster

What is the speed of the earth to escape the sun's gravity?
The escape velocity from the Sun at the Earth's distance is about 42.1 km/s. This means that for an object to escape the Sun's gravity at this distance, it would need to travel at that speed. The Earth's orbital speed around the Sun is about 30 km/s, so it is not moving fast enough to escape the Sun's gravity.
Does the air in a ball affect how fast it falls?
No, the air inside a ball does not affect how fast it falls. The rate at which an object falls is determined by gravity and the air resistance it encounters, not the properties of the air contained within the object.
Can an object travel as fast as light?
No. If something could it would have to move about 700million mph. That's why it is hard to travel to other planets.
What is useful to calculate an object's average speed when it does not travel?
When an object is stationary and does not travel, calculating its average speed is not useful since there is no displacement or time taken to travel. Average speed is typically used to measure how fast an object moves over a period of time, which does not apply to a stationary object.

What is gaining of momentum?
When an object moves really fast it gains more mass because the centre of the object increases in density. This is why planets have such a large mass, because they travel so fast around the sun.
