Its value is **9.8 m/s**^{2} on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s^{2}.

## What is the value of universal gravitational constant class 9?

The value of the universal gravitation constant is found to be **G=6.673 x 10**^{–}^{11}Nm^{2}/kg^{2}.

## Why the value of G is universal constant?

Solution : **The value of the constant of gravitation does not change with the nature, mass or the size of the material particles**. It does not vary with the distance between the two particles. It is also independent of the nature of the medium between the two particles. Hence, it is called a universal constant.

## What is the value of universal?

A value is a universal value if it has the same value or worth for all, or almost all, people. Spheres of human value encompass morality, aesthetic preference, human traits, human endeavour, and social order.

## What is the SI unit of solar constant?

## What is g in Newton’s law of gravitation?

Answer and Explanation: The G in Newton’s law of gravitaiton is the **universal gravitational constant** and it has a value of 6.664×10−11m3kg−1s−2 6.664 × 10 − 11 m 3 k g − 1 s − 2 .

## In what source G is universal?

This is Expert Verified Answer

G is known as universal constant because **it is equal through out the universe**. Its value doesn’t change . That is the force of gravitation is directly proportional to the masses of two bodies and inversely proportional to the square of distance between them.

## What do you mean by universal constant?

Definition of universal constant

: **a physical constant of wide application and frequent occurrence in physical formulas** the speed of light, c, the electronic charge, e, and the Planck constant, h, are universal constants.

## What is Capital G in physics?

The force of attraction between any two unit masses separated by a unit distance is called the universal gravitational constant. The universal gravitational constant is denoted by the symbol G and is measured in Nm^{2}/kg^{2}. The numerical value of G is 6.67 × 10^{–}^{11} Nm²/Kg².

## Is gravity constant on Earth?

9.807 m/s²

Earth / Gravity

## Why g is zero at the Centre of Earth?

Explanation: **The force due to the upper half of the Earth cancels the force due to the lower half at the center of the Earth**. Similarly, any force due to any portion of the Earth at its center will be cancelled by the portion opposite to it. As a result, the gravitational force at the center of anybody will be zero.

## Why the value of g is maximum at Pole?

**The distance from the poles to the centre of the earth is lesser than the distance from the equator to the centre of the earth**. Therefore the acceleration due to gravity is greater at the poles than at the equator.

## At what height gravity is zero?

**Gravity can never become zero except maybe at infinity**. As we move away from the surface of the Earth the gravitational force becomes weaker but it will never become zero.

## Where is no gravity in Earth?

The correct answer is **At the centre of the Earth**.

## Where is the most gravity on Earth?

Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s^{2}, while the highest is at **the surface of the Arctic Ocean**, at 9.8337 m/s^{2}. “Nevado was a bit surprising because it is about 1000 kilometres south of the equator,” says Hirt.

## Which country on Earth has no gravity?

Reverse waterfall, **Faroe Islands**

Well, there is one on the Faroe Islands, where the water seems to move upward, i.e., defying the law of gravity. In fact, the waterfall, rather than defying gravity as the name suggests, goes upside down when strong gusts of wind blows against the flow of the waterfall.

## At what distance gravity ends?

The Earth’s gravitational field extends well into space it does not stop. However, it does weaken as one gets further from the center of the Earth. The Shuttle orbits about **125 mi above the surface**, roughly the distance between Jackson and Nashville!
