# What is The Value of g?

By Harshal Vispute|Updated : August 4th, 2022

The term "acceleration due to gravity" refers to the force exerted by a heavy body on a freely falling item, denoted by the SI unit m/s2 value of g. The value of g changes from one body to another and depends on the mass and radius of the vast body. Earth's acceleration caused by gravity, or the magnitude of g, is 9.8 m/s2. According to this, an item falling freely on Earth would accelerate by 9.8 meters per second.

The term "g" stands for "gravitational acceleration." On Earth, it has a value of 9.8 m/s2. In other words, the acceleration of gravity at sea level on the Earth's surface is 9.8 m/s2. It said that location affects the value of g when talking about the acceleration of gravity.

Summary:

## What is The Value of g?

The force of gravity applied by a heavy body on a freely falling object is referred to as "acceleration due to gravity," It is represented by the SI unit m/s2 value of g. The value of g differs between different bodies and depends on the mass and radius of the enormous body. The magnitude of g, or the acceleration of Earth due to gravity, is 9.8 m/s2. This states that an object freely falling on Earth would accelerate by 9.8 meters per second. This acceleration can be attributed to the Earth's gravity. "Gravitational acceleration" is what the letter "g" stands for. Its value on Earth is 9.8 m/s2. The acceleration of gravity at sea level on the Earth's surface is 9.8 m/s2, to put it another way. When discussing the acceleration of gravity, it started that location impacts the value of g.

## Value of g FAQ's

• The acceleration due to the gravity formula is indicated by G = GM/R2, where G is the universal gravitational constant, G = 6.674 x 10-11 m3 kg-1 s-2. M is the mass of the body measured using kg. R is the mass body radius measured by m. g is the acceleration due to the gravity determined by m/s2. The mass of the moon is 7.35 × 1022Kg. The radius of the moon is 1.74×106m. Substituting the values in the formula. We get -g= 6.67×10−11×7.35 × 1022/(1.74×106)2. Thus, the value of g on the moon is g = 1.625m/s2.

• The value of G is (6.6743 ± 0.00015) × 10−11 m3 kg−1 s−2. It must be pointed out that G occupies a rather anomalous position among the other constants of physics.
