How is the gravitational constant derived
Web28 jan. 2024 · g= acceleration due to gravity, G=Gravitational constant, M=Mass of the Earth, and R=radius of the Earth. Weight of the body (on Earth)=. mass (m) ⋅ gravitational acceleration (g) Cancel out the m on both sides to get: g = G ⋅ M R2 = GM R2. Answer link. WebEarlier we stated without proof that the law of gravitation applies to spherically symmetrical objects, where the mass of each body acts as if it were at the center of the body. Since Equation 13.2 is derived from Equation 13.1, it is also valid for symmetrical mass distributions, but both equations are valid only for values of r ≥ R E r ≥ R E.

Webv2c(r) = 4πGρ0r20 3 − α (r0 r)α − 2. For α = 2 the circular velocity is constant with vc = √4πGρ0r20 and we can write the gravitational potential in Equation (3.55) in terms of vc. Φ(r) = v2clnr, (α = 2). This is an important potential that is, for obvious reasons, often referred to as the logarithmic potential.
