What is the Value of Gravitational Constant?
The gravitational constant, often denoted as G, is a key figure in physics, particularly in the field of gravitation.
The value of the gravitational constant is approximately 6.674 × 10-11 m3 kg-1 s-2.
The Universal Law of Gravitation was formulated by Sir Isaac Newton.
The gravitational constant is a fundamental physical constant that quantifies the strength of the gravitational force between two objects. It is a cornerstone in the laws of physics, helping us understand how objects attract each other with a force proportional to their masses and inversely proportional to the square of the distance between their centers.
Significance in Newton’s Law
In Newton’s Law of Universal Gravitation, G is used to calculate the attractive force between two masses. The law states that every point mass attracts every other point mass by a force acting along the line intersecting both points.
The formula is expressed as:
F= Gm1 m2 / r2
where,
- F is the gravitational force, m1 and m2 ​are the masses of the objects
- r is the distance between the centers of their masses.
