This Is Why The Speed Of Gravity Must Equal The Speed Of Light
WebThe angular speed of Earth everywhere is ω = 2 π rad 24 hr × 3600 s/hr = 7.27 × 10 −5 rad/s. Substituting for the values or R E and ω, we have R E ω 2 = 0.0337 m/s 2. This is only 0.34% of the value of gravity, so it is clearly a small correction.
