Gravity

One of the four fundamental interactions, gravity is responsible for the fact that any objects with mass attract one another. According to general relativity, it is a space time curvature, but according to quantum mechanics it is the result of exchanges of virtual gravitons.

Which layer of the atmosphere loses atoms and molecules due to weak gravity?

The exosphere is the outermost layer of Earth's atmosphere where the weakest amount of gravity allows atoms and molecules to escape into space. This layer is composed mainly of hydrogen and helium atoms that can reach high velocities due to solar radiation.

What object has the most gravity?

The one with the biggest mass and smallest size has.

Moon gravity vs earths gravity?

Moon gravity is less because the atmosphere and mass and the earths gravity is greater than the moon if you weight yourself in the earth and then you weighted yourself in the moon you would weight less in the moon you could actually float in the moon because of its atmosphere and mass

What has the most gravity in the universe?

Perhaps the most massive of all "singular" objects in the universe is a super-massive black hole.

Certainly a galaxy that has many black holes in it and billions and billions of stars has more mass and more gravity than any star or smaller galaxy. But as regards "point objects" in our uinverse. The most massive black holes, the so-called super-massive black holes, are the ones with the most gravity.

What percent of Earth's gravity does Jupiter have?

Jupiter's gravity is about 24.8 m/s^2, which is approximately 2.53 times the gravity on Earth. This means that Jupiter has about 253% of Earth's gravity.

Does the earth's gravity pull with the same force on all objects?

No. The gravitational force between any two objects depends on the product of

the masses of both objects.

Hint: That's why it's possible for two people on Earth to have different weights.

Does the Earth have more gravity than Jupiter?

Jupiter, the biggest planet in the solar system, has far more gravity than the Earth. Only the Sun has more gravity than Jupiter in our solar system.

What happens when a light moves away from Earth?

As a light source moves away from Earth, its light waves become stretched out, causing a shift towards longer wavelengths known as redshift. This is due to the Doppler effect, where the frequency of light is altered by the motion of the source relative to the observer. This redshift can indicate that the object emitting the light is moving away from us.

What describes Earth's gravity?

Earth's gravity is a force that pulls objects towards its center. It gives weight to objects and keeps the Moon in orbit around the Earth. The strength of Earth's gravity decreases with distance from its center.

What is the gravity of Pluto in relation of earth gravity?

Pluto's force of gravity is equal to 0.58m/s2, whereas the force of gravity on Earth is 9.81m/s2. Thus, the gravity on Pluto is about 6% that of the gravity on Earth.

How does the center of gravity affect rockets?

The center of gravity of a rocket is critical for stability during flight. If the center of gravity is too high or too low, the rocket may become unstable and veer off course. Proper placement of the center of gravity ensures that the rocket will fly straight and true.

What changes occur to gravity as you go further South in the Southern Hemisphere?

As you move from a pole toward the Equator the Earth's spin will act against the force of gravity, so that the net gravity will fell less as you approach the Equator. As you move away from the equator towards a pole (as in moving south, when in southern hemisphere), the spin effect becomes less, so the feel of gravity will increase. The amount of change is slight. Also, the equator is a little farther away from the center of mass than the pole, making the gravitational pull at the equator a little less, as well.

Why is gravity important to the earth?

== == If the sun's gravity dissapeared, then, even if we still got light and warmth, the earth would stop circling the sun and start floating away into space. It would get colder and colder, and finally the earth would float too far away and freeze.

What happens when the planets stop moving?

If the planets were to suddenly stop moving, they would no longer orbit the sun due to the lack of gravitational pull. Without their orbital motion, the planets would likely drift off into space in a straight line until they either collided with something or were gravitationally attracted to another object. This scenario is purely hypothetical as the laws of physics dictate that the planets will continue to orbit the sun.

Why does ganymede have the most gravity?

Because it is the biggest moon in the solar system. If you meant "moon" in your question, then your answer is here.

How did Charles Darwin discover gravity?

Charles Darwin did not discover gravity, that was Sir Isaac Newton in the 17th century. Charles Darwin was a naturalist and biologist known for his work in the theory of evolution through natural selection, not for discoveries related to gravity.

What are the 5 examples of gravity?

Gravity is a force which, as far as we have been able to determine, operates everywhere in the universe and is felt by everything that has mass, so I am not sure why you think that there are exactly five examples of gravity. There are limitless examples of the functioning of gravity, but there is only one force of gravity.

True or false Particles in a nebula are attracted to one another because of gravity?

True. Particles in a nebula are attracted to one another due to gravity, which causes them to clump together and form larger structures like stars and planets. This process is essential in the formation of celestial bodies in space.

How would life on earth change if Earth's gravity changed?

There is a whole book to be written speculating about how life would be if Earth's gravity was weaker or stronger. Let's assume weaker gravity for this discussion - whatever applies to weaker gravity probably applies in reverse for stronger gravity.

The most obvious effect of weaker gravity on higher animals is that they could be larger. The largest land animals are, in part, limited in their size by the strength of the bones in their legs, and in the ability of their bodies to deal with gravity (for example, in simply holding the internal organs in place). With weaker gravity, bones that are made in the same way as those in existing animals could hold up much greater weights, so animals could be truly enormous by our standards.

However, like anything in science, there are details that we would also have to consider that could change things considerably. Lower gravity could mean that lighter gases could escape Earth's atmosphere into space (as hydrogen and helium do now), changing our atmosphere in ways that we might not expect. The effects could be higher or lower temperatures, the formation of lower or higher amounts of ozone in the ozone layer that could increase or decrease damaging UV radiation from the sun, or even a requirement for living creatures to exist in a reducing atmosphere - the opposite of the oxidising atmosphere that we have now, and more like the atmosphere of the early earth.

Other effects would result from the physical form of the Earth - lower gravity would mean higher mountains and so probably a wider variety of ecological environments, different coverage of the Earth with water, etc.

In short, the differences could be very significant, and probably unpredictable - and the ones that are given here are just for starters.

How did Issac newton find out about gravity?

Isaac Newton discovered gravity by observing an apple falling from a tree, which led him to formulate his law of universal gravitation. He realized that the same force that causes objects to fall to the ground also governs the motion of planets in space.

Is there gravity near the sun?

Yes, there is gravity near the sun. Gravity is a fundamental force that exists between all objects with mass, and the sun's mass creates a gravitational field that affects all objects in its vicinity, including planets and other celestial bodies.

What country was gravity discovered?

Well, back when the first human was around, I don't think there were any countries. However, Gnarl Tukee of the Gnishmash clan I believe discovered it a few seconds before he fell to his death.

How can you see gravity?

Gravity is a force that cannot be seen directly, but its effects can be observed. We can see the effects of gravity when objects fall to the ground, planets orbit around stars, or when tides are created in the oceans due to the gravitational pull of the moon.
