Assuming there is no air resistance, if an object starts at a speed of 11.2 km/sec, it can escape the gravitational field of Earth. This "escape velocity" is different for different planets, moons, etc.

Is gravity an instantaneous force?
No. In Newtonian physics, gravity is treated as an instantaneous force, but in General Relativity, gravity propagates at the speed of light in a vacuum. There's some debate on whether it's actually been experimentally shown that the "speed of gravity" is the same as the speed of light in a vacuum or not. However, there is fairly clear experimental evidence that it does have a speed and is not instantaneous. See the Wikipedia article in "Related Links" for a much longer and more detailed discussion.
How much force to lift 50 kilograms onto a shelf 3 meters high?
The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

Which gravity speeds up a moving object?
Gravity will speed up a force if gravity acts in the same direction as the object is already moving - for example, if the object is already moving downward - and if counterforces (such as air resistance) don't interfere too much.
How much thrust does it take to push 1 pound?
1 pound of thrust is the force required to hold 1 pound of a material stationary in the air against the effect of gravity. This is only in ideal case(no effects of atmosphere) and excluding the weight of the engine which generates that thrust.

How much energy is required to break the gravity?
nun i think
What is the speed of 110 gravity?
Gravity is measured, not in terms of speed, but of acceleration. For example, Earth gravity is 9.8 meters/second2. 110 times that much would be called, informally, "110 g".

What a cause a boy climbing a hill to be so tired?
Gravity. When you're climbing up a hill, you're pretty much competing against gravity.
How much speed of Internet is required for CAPTCHA entry?
I am doing this captcha entry, and it requires minimum of 512kbps speed of Internet..........
How much is the force of a pull against poo?
Poo is subject to the force of gravity, 9.8 m/s2.
What does acceleration refers to in science?
It is a property which was discovered by Newton. In it a thing gains speed automatically while it is being put in effort from a ramp, or thrown from height. It get it's speed from gravity.(Gravity has three properties, one is acceleration).
How much time is required for a speed post to reach Bangalore from kanpur?

Why is it easier to ride your bicycle down?
This is because gravity is pulling you down, so you don't have to pedal as much downhill. Uphill, on the other hand, gravity is STILL pulling you down, so you have to fight to move forward AND to move against gravity.

1 pound of thrust is the force required to hold 1 pound of a material stationary in the air against the effect of gravity. This is only in ideal case(no effects of atmosphere) and excluding the weight of the engine which generates that thrust.
