Why does an objects gets attracted towards moon when it leaves the earth's gravitational field?
The moon orbits Earth because it is held there by Earth's gravity. The moon is going fast enough that it won't hit Earth, but at the same time is being pulled back in at the same rate it flies away. The same is true for why Earth itself doesn't fly into the sun. the sun is MUCH MUCH MUCH further away than the earth is, so it is attracted to earth because the difference in size and gravity favour the earth. If it was to be attracted to the sun, the sun would need to be bigger or closer (both of which it is doing at aconstant rate, but very gradually over a long perios of time)
How fast is earth rotating?
well when the earth was being formed there would have been a spinning bit of rock which would have had enough gravity to attract more rocks which crashed into it and joined with it and then the gravity would have been stronger so more rocks would have come and some of those rocks would hit the spinning ball at such an angle that it caused the ball of rock to spin faster and because there was no friction or air resistance in space to stop it, the earth just kept on spinning. Pheww!! that was a long sentence.
Explain what keeps the moon orbiting Earth?
Because the moon moves with a certain speed in its orbit, that orbital motion produces a centrifugal force which opposes the attraction of gravity. The balance between gravity and centrifugal force keeps the moon in orbit. The moon continues to orbit at the speed it does, because of its inertia. Moving in the vacuum of space, the moon does not encounter resistance to its motion. There is, however, some energy lost as a result of tidal forces, and that will, over a very long period of time, eventually alter the moon's orbit.
What is the force that holds the solar system together?
Gravity and speed. The mass of the sun is 330,000 times the mass of the Earth, and 1048 times the mass of Jupiter. This prevents the planets from moving away. What prevents them from falling closer to the sun is the speed at which the planets are moving, which is 30 kilometers a second for earth.
What scientific concept did Indian astronomers prove long before europeans did?
The Earth is round the earth was round
What is the strength of the gravitational pull on your body?
The strength of the gravitational pull on your body is approximately 9.81 meters per second squared (m/s^2) on Earth. This is commonly referred to as the acceleration due to gravity, and it is what gives us our weight on the Earth's surface.
What day of the year does the earth have the least gravity?
As long as the Earth's mass doesn't change, neither does its gravity, regardless of what day it is.
What is the advantage of having a long tap root?
becaus of the gravity of the earth
How does gravity affect length of day?
It doesn't. For instance ... Earth & Venus have almost the same gravity yet Venus' day is about a year long Whereas Mars has but a quarter of Earth's gravity and its day is almost identical.
Does the moon have smaller gravity than the earth?
Yes. The moon has 6 times less gravity than the earth, so if you were to long-jump 3 feet on the earth, you would go 18 feet on the moon.
Why would the earth lose it's gravity if it's core cooled?
The Earth's gravity is not solely dependent on the temperature of its core. Gravity is determined by the mass of the Earth and its size. Even if the core were to cool, the Earth would not lose its gravity as long as its mass and size remain constant.
What is a principle that has been scientifically verified?
One principle that has long been scientifically verified is that of gravity. Scientists agree that the law of gravity operates on earth.
How will humans be affected by gravity if you leave earth?
Gravity might have a hold on you or you will grow a couple of inches and lose weight. It depends on how long you are staying in space.
Why don't we notice a difference between mass and weight on earth?
We don't notice a difference between mass and weight on Earth because the acceleration due to gravity is constant on the surface of the Earth. Weight is the force of gravity acting on an object's mass, so as long as the acceleration due to gravity remains constant, the weight of an object will be proportional to its mass.
Is the force of gravity the same on an object fifty miles above the earth?
Yes. Gravity is a constant force. It never changes as long as you are within it's pull.
How do you reduce gravity on an object?
The only way to do that is to physically take it away from the Earth. As long as the object remains on the Earth, you can apply additional forces to it, to combine in various ways with the force of gravity and make the object move as you want it to, but there's nothing you can do to change the force of gravity on it.
Why does gravity pulls objects to earth?
Gravity is the cause of a pair of forces that attract any two specks of mass toward each other. The forces act along the line between the centers of the objects. As long as you're anywhere near Earth, the forces of gravity pull the Earth toward the center of you, and pull you toward the center of the Earth (and they're equal).
