If gravity is working in both directions why does the Earth move but the Sun does not?

That isn't exactly how it works.* Gravity works in both directions.
* The Earth is pulled towards the Sun, and the Sun is pulled towards Earth.
* Since the Sun has about 333,000 times the mass of Earth, the effect on the Sun (acceleration) is 1/333,000 times as much as the effect on Earth.

∙ 6y agoActually the earth and sun both move about their common centre of gravity. But, because the mass of the sun is 333,000 times that of the earth, the effect of the force on the sun is much smaller - so small that the sun's motion is not noticed.
However, the fact that planetary gravity affects the motion of stars is used to detect exo-planets - planets outside the solar system.

Can a spring tide occur when the gravity of the Sun and Moon pull Earth's surface in opposite directions?
Yes. Tidal bulges occur on both the near side and the far side of the affected object and are largely indistinguishable from one another.
What does earth have that Venus and mars both lack?
venus and mars don't have gravity as earth and they don't have required conditions to live
Does Neptune have an impact on Earth?
The main thing it does is it prevents comets and asteroids from hitting earth by pulling them towards itself with its enormous gravity. Some astronomers also think its gravity changes the paths of objects that would otherwise hit earth.
What are the two positions on earth where both latitude and longitude can be written correctly without any directions?
The North and South Poles.
How does Venus' atmosphere and gravity compare to earth's?
Venus' atmosphere is similar to Earth's as it has one predominant gas. Venus' is comprised of mainly Carbon Dioxide, around 96%. Whereas Earth's atmosphere is mainly Nitrogen, around 78%. Both atmospheres contain levels of other gases but the main difference is the presence of Oxygen on Earth, around 21%. Gravity on both planet's is very similar. Measured at the equator, Earth's gravity is 1g or 9.81NKg-1 , the SI unit for gravitational field strength. Venus' gravity is around 0.9g or 8.87NKg-1
What would the gravity be on a 1 kg block?
That depends on where it is. If it's on the surface of the Earth, then the forces of gravity in both directions between the block and the Earth are about 9.807 newtons (2.204 pounds). But if you take the block to the moon's surface, for example, then the forces of gravity in both directions between the block and the Moon are about 1.62 newtons (5.84 ounces).
The mesurement of the force of gravity on an object is the objects?
The magnitude of the equal gravitational forces in both directions between the earth and any object on it is the object's "weight".
What will happen to the value of g if the compound pendulum is taken nearer to the centre of earth?
The acceleration of gravity (value of 'g') is maximum on the earth's surface, and it decreases from there in both directions ... up into the air or down into the earth.
When earth revolve around the sun in an orbit is it due the gravitation of sun?
It's due to the forces of gravity in both directions between the Sun and the Earth. Comment: The gravity that matters in this case is the Sun's pull on the Earth. That's what keeps Earth in orbit, combined with the Earth's velocity, at about 90 degrees to the direction of the Sun.
What is the pull of gravity on earth a direct result of?
The force of gravity is mutual between every pair of masses. The strength of the force is proportional to the product of the masses, and it's equal in both directions. The 'pull' toward the earth that you feel is the force of gravity between the earth's mass and your mass. The strength of the pull is proportional to the product of your mass and the earth's mass, and the earth feels the same pull toward you.
Who has gravity the earth or moon?
both
How far does gravity extend from the surface of the moon?
There is a force of gravity in both directions between every pair of objects, attracting them toward each other. There's no limit on the distance. There is a force of gravity in both directions between the lint in your pocket and the smallest grain of sand on the beach on the far side of the farthest planet orbiting the farthest star in the farthest galaxy from Earth, attracting them toward each other.
What is the direction of gravity?
The gravitational forces between two objects act in both directions along the line between their centers of mass. In our daily experience, where one of the objects is always the Earth, we call one of those directions "down" and, as relates to the forces of gravity, we ignore the other direction completely.
How much pressure does gravity exert on your body?
The force of gravity between me and the earth is the same in both directions. I'm pulled down toward the center of the earth by a force of 190 pounds, and the earth is pulled up toward the center of me by a force of 190 pounds. I call that force "my weight on earth", and it's also the earth's weight on me.
What does the force caused by gravity pulling down on an object cause an object cause an object to have?
The forces of gravity in both directions between the Earth and an object on it are equal,and act in opposite directions. The force from the object toward the Earth is what wecall the object's "weight" on Earth. The other force is so universally ignored that it isalso almost universally misunderstood. It acts in the direction from the Earth towardthe object, it is quite literally the Earth's weight on the object, and it is exactly equalto the other one.
Do venus and earth both have gravity?
Yes. All planets have noticeable gravity.
What planet has twice the gravity of earth?
Despite the fact that Uranus has a mass 14.5 times Earth's mass, its surface gravity isless thanEarth's.Jupiter and Neptune both have more "surface gravity" than Earth.
