Can anyone give me a definition and explain why it appears in Newtons law of gravitation.

The actual value of and error associated with Newton's gravitational constant is the source of some disagreement. Perhaps someone more knowledgeable about attempts to measure G would like to expound on this.
The Universal Gravitational Constant, denoted by the symbol G, is a fundamental physical constant that is used to measure the strength of the gravitational force between two objects.
The Universal Gravitational Constant is typically measured through experiments involving the motion of objects under the influence of gravity. One common method is the Cavendish experiment, which involves measuring the deflection of a torsion balance due to the gravitational force between two masses.
The Universal Gravitational Constant is important because it helps us understand and quantify the force of gravity, which is a fundamental force of nature. It plays a crucial role in fields such as astrophysics, planetary science, and engineering.
The current accepted value of the Universal Gravitational Constant is approximately 6.674 x 10^-11 m^3/kg/s^2. However, this value is subject to slight variations due to the difficulty in accurately measuring it.
The Universal Gravitational Constant is a key component of Newton's Law of Universal Gravitation, which states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The value of G determines the strength of this force.
