WebMar 20, 2024 · gravitational constant (G), physical constant denoted by G and used in calculating the gravitational attraction between two objects. In Newton’s law of universal gravitation, the attractive force between two objects (F) is equal to G times the product of their masses (m1m2) divided by the square of the distance between them (r2); that is, F … WebIn science and engineering, the weight of an object is the force acting on the object due to acceleration or gravity. [1] [2] [3] Some standard textbooks [4] define weight as a vector quantity, the gravitational force acting on the object. Others [5] [6] define weight as a scalar quantity, the magnitude of the gravitational force.

In SI units, its value is approximately 6.674 × 10 −11 m 3 ⋅kg −1 ⋅s −2. The modern notation of Newton's law involving G was introduced in the 1890s by C. V. Boys. The first implicit measurement with an accuracy within about 1% is attributed to Henry Cavendish in a 1798 experiment. See more The gravitational constant (also known as the universal gravitational constant, the Newtonian constant of gravitation, or the Cavendish gravitational constant), denoted by the capital letter G, is an empirical physical constant involved … See more The gravitational constant is a physical constant that is difficult to measure with high accuracy. This is because the gravitational force is an extremely weak force as compared to other fundamental forces at the laboratory scale.
