what is the value of universal gravitational constant g
Gravitational constant The measured value of the constant is known with some certainty to four significant digits. In SI units its value is approximately 6989667400000000000♠6.674×10−11 N·kg–2·m2.
g-force Human tolerances depend on the magnitude of the g-force, the length of time it is applied, the direction it acts, the location of application, and the posture of the body.[7][8]:350
Gravitational constant According to Newton's law of universal gravitation, the attractive force (F) between two point-like bodies is directly proportional to the product of their masses (m1 and m2), and inversely proportional to the square of the distance, r, (inverse-square law) between them:
Pi Ï€ is commonly defined as the ratio of a circle's circumference C to its diameter d:[9]
