Value of g

What is the value of g on Earth?

The value of gravitational acceleration (g) on Earth is approximately 9.81 meters per second squared (m/s²).

How does g vary from planet to planet?

The value of g varies across different planets due to differences in their mass and radius. For example, g is 3.7 m/s² on Mercury and 24.79 m/s² on Jupiter.

What factors influence the value of g?

The value of g is influenced by the mass of the celestial body and its radius. A larger mass or a smaller radius results in a higher value of g.

Is the value of g constant?

The value of g is not constant and varies with altitude, depth, and geographical location due to Earth’s shape and density variations.

Why is the value of g important in physics?

The value of g is crucial for calculating forces in mechanics, understanding planetary motions, and designing structures and vehicles that operate under gravity.

What is the value of g on the Moon?

On the Moon, the value of g is about 1.62 m/s², much lower than Earth’s due to its smaller mass.

How is g measured?

The value of g can be measured using pendulums, gravimeters, and through orbital mechanics by observing the motions of satellites.

The acceleration felt by a free-falling object due to the gravitational force of the mass body is called gravitational acceleration. It is denoted by g and calculated using SI unit m/s². The value of g depends on the mass of the body and its size. Its value varies from body to body. In this article, we will learn about the value of g in physics in detail.
