Newton's force law becomes cluttered with unintuitive constants! $\begingroup$I wonder if there is a nice way to perform an asymptotic analysis of the nonlinear pendulum equation to show why, under these assumptions, $g$ should be about $5\%$ smallerthan $\pi^2$.$\endgroup$ - Ian Feb 10 '16 at 17:37 2 $\begingroup$Coincidence. 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 in the calculation of gravitational effects in sir isaac newton 's law of universal gravitation and in albert … Question 2. Immediately we recognize that 4 π r 2 is simply the surface area of a sphere of radius r. But that's only in 3 dimensions. vertical circles. The equivalent of the Julian Date for Mars is the Mars Sol Date. The physical reason for the appearance of a $4\pi$ somewhere in the theory is the spherical symmetry of the problem and is discussed more in other answers . 4. How should the gravitational constant "big G" be included, 4pi? But by defining G ∗ = 4 π G Newton's law of gravitation can be reformulated as such: F = G ∗ m 1 m 2 1 4 π r 2. Measuring the gravitational constant is a common experiment conducted by introductory physics students by measuring the gravitational attraction between two objects. A coupling constant (or an interaction constant) is a parameter in the field theory, which determines the relative strength of interaction between particles or fields. Since the two forces must be equal, mV^2/r = µm/r^2 or V^2 = µ/r. I got 1.5 x 10^29.
