Homework Statement
Assume that the center of mass of the Earth moves with approximately constant velocity with respect to the fixed stars, and that [itex]\mathbf{\omega}[/itex], the angular velocity of the earth, is constant. Rederive the terrestrial equations of motion
[tex]\mathbf{F}'+m\mathbf{g}[/tex][tex]m\ddot{\mathbf{r}}-2m\mathbf{\omega}\times\dot{\mathbf{r}}[/tex]
By writing Newton's laws in a body-fixed frame with the origin at the surface of the earth.
Homework Equations
For a particle with coordinates [itex]\mathbf{r}_0[/itex] in the inertial frame and [itex]\mathbf{r}[/itex] in the body-fixed frame, where the origin of the body fixed frame is at the instantaneous point [itex]\mathbf{a}[/itex] with respect to the inertial frame.
[tex]\mathbf{r}_0 = \mathbf{a}+\mathbf{r}[/tex]
The Attempt at a Solution
I'm pretty confused on where to start here. I know that in the inertial frame [itex]\mathbf{F}=m\mathbf{A}[/itex]. Could anyone help get me started, or point me towards some literature on this?
