Gravity

I guess mother nature did. The first mathematical description of gravity came from Sir Isaac Newton, so the modern study of the effects of gravity were initiated by him.

Gravity is the force by which a planet or other body draws objects toward its center. The strength of gravity depends on the mass of the objects and the distance between them. It is responsible for keeping celestial bodies like planets and stars in orbit.

Yes, particles in a nebula are attracted to one another due to gravity. As the particles come together under the influence of gravity, they can clump together and eventually form stars and planets. This gravitational attraction is an essential process in the formation of celestial objects in space.

The center of gravity for a triangular region is at the point where the three medians of the triangle intersect. The medians are the line segments that connect each vertex of the triangle to the midpoint of the opposite side. This point is also known as the centroid of the triangle.

Much weaker. Pluto is a dwarf planet and much less massive than earth, so it has lesser granitational force at it's surface.

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.

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.

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.

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.

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.

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

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.

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.

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.

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?

The one who discovered the Law Of Gravity is SIR ISAAC NEWTON

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.

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.

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.

The one with the biggest mass and smallest size has.

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
