WebOct 25, 2024 · Gravitational Constant. The gravitational constant was developed as part of the law of gravity developed by Sir Isaac Newton. Measuring the gravitational constant is a common experiment conducted by introductory physics students by measuring the gravitational attraction between two objects. G = 6.67259 x 10 -11 N m 2 /kg 2.
WebTo do this, the 4 π factor has simply been "built into" the (SI unit) definition of the universal constant for permeability of the vacuum, μ 0 = 4 π × 10 − 7 H / m, from which we can express Coulomb's constant as k= 1 4 π ϵ 0.
