To understand the effect of altitude, let us revisit the gravitational force equation At a height h from Earth’s surface, this equation modifies to Therefore, by repeating the same steps as above, we get Since GM/R2is the acceleration g on the Earth’s surface The above expression is the acceleration due to gravity at a height above Earth’s surface....
Recall the expression for acceleration due to gravity at the surface of the Earth Earth’s mass M can be written in terms of density ρ and volume 43πR343πR3. Therefore, At a distance d below the Earth’s surface, the acceleration due to gravity is given by Diving one equation by the other Note that at the Earth’s surface, d = 0 and gd= g
Suppose an object with mass m lies on the Earth’s surface at a latitude θ. Let ω bet the angular velocityof the Earth. For the non-inertial frame, there exists a centrifugal force on the object given by Where r is the shortest distance of the object from the axis of Earth’s rotation. It is also the radius of the circular path that the object traces...
