Why is there no gravity on moon?
The moon does have gravity, but it is much weaker than Earth's gravity. This is because the moon is smaller and less massive than Earth. Astronauts can still walk on the moon because it has enough gravity to keep them on its surface.
How do astronauts train for zero-gravity?
Astronauts train for zero-gravity by using specialized simulators like the Neutral Buoyancy Lab's giant pool, which allows them to practice spacewalks underwater to simulate the weightlessness of space. They also use parabolic flights on aircraft that create brief periods of weightlessness. Additionally, they undergo physical conditioning and strength training to cope with the physical demands of living and working in microgravity.
Why Venus is the same size of earth and the same gravity?
Since Earth and Venus are roughly the same size AND have roughly the same mass,
they have roughly the same gravity. The acceleration of gravity on the surface of
Venus is 90.3% of what it is on Earth's surface.
Where is Center of gravity on a bottle rocket?
The center of gravity of a bottle rocket is typically located towards the nose cone or front of the rocket. This helps stabilize the rocket during flight, ensuring that it flies in a straight trajectory. Placing the center of gravity too far back could cause the rocket to become unstable and veer off course.
How does the line of gravity affect the stability?
If an athletes line of gravity moves outside of his/her base of support then they will no longer be able to maintain that body position. Eg; during a headstand the performers centre of mass must remain between the triangle of the hands and head. If it moves outside of this then the balance will break down.

The acceleration due to gravity at the equator?
about 9.795m/s2 but
9.8m/s2 is almost always used.
Note: centripetal acceleration (from the earth's spin) cause apparent gravity to be about 0.3% less than actual gravity (about 9.767m/s2) at the equator
you can find the acceleration of gravity on any planet by the equation:
a=G(M/R2) where 'a' is the acceleration due to gravity, G is the gravitational constant (about .0000000000667), M is the mass of the earth ( or other planet), and R is the radius of the earth (or other planet)

What happens when the outward force of pressure wins out over gravity in an old star?
When the outward force of pressure wins over gravity in an old star, the star will expand and cool, becoming a red giant. This process occurs as the star exhausts its nuclear fuel and transitions to a different phase of stellar evolution.
On earth, the gravity is greater in earth
The ratio of the earths gravity to the suns gravity?
No meaningful comparison is possible without specifying that the distance from both
bodies will be the same at the moment of measurement.
If you measured the acceleration due to gravity (or your weight) some distance from
the sun, and then measured the acceleration due to gravity (or your weight) at the
same distance from the Earth, you would find that the measurement in the vicinity
of the sun is about 332,982 times the corresponding measurement at the Earth. It
doesn't matter what the distance is, as long as both are the same.
The suns gravitational pull causes the earth and other planets to the sun?
Yes, the sun's gravitational pull is what keeps Earth and the other planets in our solar system in orbit around it. This gravitational force is what maintains the planets' paths and prevents them from moving off into space.
What fraction of the moons gravity is the moons gravity?
The moon's gravity is essentially identical to 100% of the moon's gravity,
and results in gravitational forces on its surface that average about 16%
of the corresponding forces on the Earth's surface.
How does plant respond to light and gravity?
Yes gravity does have effect on plants because the stems always goes up on earth and the roots do down. But in space plants don't know which way is up and which way is down due to the lack of gravity. The real question is how can plants tell which way is up and which way is down due to lack of gravity?
How g becomes zero at the centre of earth?
At the center of a sphere, for every dot of mass attracting you toward it, there's
another dot of mass at exactly the same distance from you in exactly the opposite
direction, attracting you toward it and canceling out the first one.
Who is the one who discovered the law of gravity?
The one who discovered the Law Of Gravity is SIR ISAAC NEWTON
Did Al-Khazini and Al-Biruni found the science of gravity?
No, Al-Khazini and Al-Biruni did not found the science of gravity. Gravity as a concept was famously formulated by Isaac Newton in the 17th century through his law of universal gravitation. However, both Al-Khazini and Al-Biruni were influential scholars in the fields of astronomy, mathematics, and physics in the Islamic Golden Age.
Does how fast earth spins effect gravity?
There is no effect to gravity due to earth fast spins because gravity is other thing and spin of earth is different thing. So we could not compare to each other. Gravity is made of mass of earth and spin of earth is due to sun, as earth revolving around the sun.
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.
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.
