How to calculate G value?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
To calculate the gravitational constant G, scientists use precision experiments like the Cavendish experiment, which measures the gravitational attraction between known masses at known distances. The currently accepted value is G = 6.674 × 10⁻¹¹ N·m²/kg². You can also calculate local g (acceleration due to gravity) using g = G × M / r², where M is Earth's mass and r is the radius including your altitude.
