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[tex]\theta[/tex])[tex]\omega[/tex] square, and g'
at the poles,[tex]\theta[/tex] =90 degree, therefore, g' = g which is 9.81
at the equator [tex]\theta[/tex]=0, therefore, g' = g- R omega square
what I couldn't understand is that why the components of g are not perpendicular to each other.
can we resolve a force into components which are not perpendicular to each other ?
