As the name suggests, the gravitational constant has a constant value which is used in the equation of Newton’s Law of Gravitation. In this article, we will learn about the definition and value of the gravitational constant.
Where, The gravitational constant is also known as the universal gravitational constant, the Cavendish gravitational constant and the Newtonian constant of gravitation. Gravitational constant is denoted by the letter ‘G’. In classical format, the gravitational constant can be derived from Planck’s length, mass, and time.
Know the gravitational constant (proportionality constant) in Newton's law of universal gravitation with explanations and examples. Learn about gravitational constant at BYJU’S.
Gravitational constant is t he universal gravitational constant (G) that relates the magnitude of the gravitational attractive force between two bodies to their masses and the distance between them.
Dimensions of Universal Gravitational Constant - Click here to know the dimensional formula of universal gravitational constant. Derive its dimensional expression with detailed explanation.
The universal law of gravitation states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
Gravitational constant, denoted by the letter 'G', is a physical constant involved in the calculation of gravitational effects. According to Newton's law of universal gravitation, the gravitational force acting between two masses m1 and m2, separated by a distance R is given by. F= Gm1m2 R2 where G is the universal gravitational constant.
