What is value of Gravitational constant?

CONCEPT:

• Newton's law of Gravitation: It states that everybody in this universe attracts every other body with a force, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
  • The direction of the force is along the line joining the particles.

The magnitude of the gravitational force F is given by:

\(F = G\frac{{{M_1}{M_2}}}{{{R^2}}}\)

Where

G = universal gravitational constant,

M1 = mass of 1st body,

M2 = mass of 2nd body

R = distance between the two bodies.

 Explanation:

From the above explanation, we can see that,

• Gravitational constant = 6.67 × 10-11 N m2/kg2
• G is called the Universal gravitational constant.
• It is the force between two objects which have some mass and distance between them.
• Sir Issac Newton gave his laws of motion, equations of motion and theory of gravity in his book Principia.
