    Undergrad Variation of gravity along latitude

    In another word, mg and centripetal force are two different forces act on a particle and mg' is the resultant force experienced by the particle?

    Graduate Spinning and rotation of planets

    consider two planets, planet X and planet Y with masses, Mx and My separated with distance, D and they orbits about the centre of mass of the system which remains stationary. we know that period of orbit for X and Y are the same because they are always collinear with the centre of mass...

    that term is centripetal force

    Undergrad Variation of gravity along latitude

    Factor contributes to variation of gravity along latitude is: 1. shape of the earth 2. rotation of the earth gravitational field strength is resolved into two components, (R cos\theta)\omega square, and g' at the poles,\theta =90 degree, therefore, g' = g which is 9.81 at the equator...
