How can rockets overcome the earth's gravity?
Exactly the way you do it when you walk up stairs ... use your engines tocreate a force greater than your weight and opposite to the force of gravity.
Where on Planet Earth such that gravity fall up rather then fall down?
-- Wherever you are on earth, the force of gravity ... that is, your "weight" ... always pulls in the directiontoward the center of the earth. That's toward the ground between your feet.-- How do we know which way is "down" anyway ? We call "down" the direction in which your weightpulls, the direction in which a stone moves when you drop it. So by definition, whichever way gravitypulls, that's the direction you call "down".
How do austronauts overcome gravity when leaving earth?
By using rocket motors to apply an upward force to their ship that is greater than the downward force of gravity. Exactly what you do with your leg muscles when you want to propel your own mass up a flight of stairs against the force of gravity.
Which force pulls everything down to earth?
which force pulls everything down the earth answer
We know that the gravitational force of the earth pulls objects down we see them fallin down but don't see objects moving up Why?
Objects fall down due to the force of gravity pulling them towards the Earth's center. Objects don't appear to move up on their own because they need a force stronger than gravity, such as a person or a machine, to counteract gravity and lift them up. Without such a force, objects will naturally fall towards the Earth.
How gravity affects firework rockets when it is its way up?
gravity pulls down a rocket
How does rocket shoots up while the gravity is strong?
By generating an upward force that's greater than the downward force of gravity. Exactly the same way you walk up stairs while the gravity is strong.
Why object fall to the ground?
Gravity pulls them down. Newtons Law of Gravity: what goes up must come down. objects fall to the ground because of gravity
Why do things fall down instead of up?
Gravity.
Why when throw a stone up it comes down?
gravity.
What is the Gravity in horse jumping?
You come up, you come down.
What makes roller coasters speed up and down?
Gravity...
What pushes up if gravity pushes down?
Gravity pulls "down" and the opposite force is provided by whatever is beneath the object.
How does the sun stay up in the air?
It stays up in the air because its in space-where there's no gravity whatsoever. so, it stays up as there is no gravity to pull it down.
How does gravity affect the weight of matter?
It's a very direct relationship; weight is caused by gravity. weight = mass x gravity Therefor, if gravity goes up and mass stays constant weight, goes up. And the reverse is true if gravity goes down and mass stays constant, weight goes down.
Why does a bus going down is faster than the going up?
Because they're both being acted on by gravity. The one going down is faster, because gravity is pulling it down in addition to the motor propelling it forwards. The one going up is having to counteract the force of gravity trying to pull it back down.
What is the effect of gravity on a person in elevator?
The effect of gravity on a person in an elevator is exactly the same as it is anywhereelse. The person and the Earth are attracted toward each other by equal forces whosestrength depends on the product of their masses and the distance between their centers.The person feels heavier when he starts a trip going up or finishes one going down, andhe feels lighter when he starts a trip going down or finishes one going up. But that's theeffect of the elevator, not the effect of gravity.
